Regent's Park and Primrose Hill

What opened in 2026

The Queen Elizabeth II Garden is the first substantial addition to the park in decades. It takes up about two acres off The Broad Walk, behind the espresso bar near the Avenue Gardens, on the site of the park's former plant nursery — decommissioned in 2018 when the Royal Parks moved its growing operation to Hyde Park. Planning permission was announced in August 2024; the garden was unveiled by the Princess Royal on 21 April 2026, the centenary of the Queen's birth, and opened to the public on 27 April 2026.

It was designed by HTA Design with the horticulturalist Noel Kingsbury and the architects Tate + Co, and built for about £5 million raised charitably rather than from public funds. The planting is chosen to survive without irrigation; a redundant water tower has been converted into a roost for birds and bats; steel from the demolished glasshouses was reused in the structures. There are four entrances and a new Changing Places toilet.

Behind it sits a piece of work worth knowing about. From March 2025 the Royal Parks ran a planting trial on the same ground, growing four drought-tolerant species — burnet rose, lesser calamint, atlas fescue and a daylily — in two media made from crushed concrete recovered from those same glasshouses, blended with soil at four parts to one and at three parts to two. The garden is the result of the trial, not a decoration laid over it.

York Bridge reopened in mid-April 2026 after a two-phase restoration, and the traffic arrangement has changed permanently. Vehicles may now cross in one direction only, from the Outer Circle towards the Inner Circle, and must leave the Inner Circle by Chester Road; a contraflow lane carries southbound cyclists; pedestrians use it both ways. St John's Lodge Garden also reopened in the spring of 2026, after repairs to the steps down to the sunken lawn and heavy pruning.

A development that half failed

The land was part of the manor of Tyburn, held by Barking Abbey until Henry VIII appropriated it at the Dissolution in the 1530s and kept it as a hunting ground called Marylebone Park. It was disparked in 1668 and let to tenant farmers for hay and dairy, which is what it stayed for about a hundred and fifty years. The ground immediately before Nash was farmland, not parkland.

The leases fell in around 1810 or 1811 — Camden's conservation area appraisal says 1811, the London Gardens Trust says 1810 — and the Crown's commissioners turned to John Nash, appointed their architect in 1806. The scheme was commercial: a landscaped park, ringed and partly filled with grand houses, whose sale and rents would pay for the whole thing and return a profit. Work began in 1811 and the layout was finished by 1827. Regent Street was driven through to connect the Prince Regent's Carlton House to his new park, and the park carries his title.

Much of it never happened. There was to be a palace for the Prince Regent, an ornamental basin and a Great Circus of houses at the southern end; none of the three was built. The villas were cut back drastically — eight went up, on Historic England's and the Royal Parks' account — and how many were proposed is not settled. The figures in circulation are twenty-six, forty, about fifty and fifty-six, each from a source that ought to know. Park Crescent shows the problem in miniature: its builder, Charles Mayor, went bankrupt after six houses, only the southern semicircle was completed, and Park Square was later laid out where the northern half should have stood.

On the date of the plan there is a trap. The register entry cites Nash, 1812, and most accounts follow it, but Sir John Summerson identified a plan signed by Nash and dated March 1811 as the earliest known version of the design, writing in Architectural History in 1977. The 1812 drawing is the published form of a scheme already a year old.

The park opened to the public in 1835, and only partly: the east side first, initially two days a week. It passed to the Ministry of Works in 1851.

The terraces, and how much of them is original

The white stucco terraces around the Outer Circle are the park's architecture, and their attributions are got wrong in both directions. Nash set the scheme and designed most of them — Hanover Terrace of 1822 to 1823, Sussex Place completed in 1823, Cambridge Terrace of 1825, York Terrace West and Gloucester Gate of 1827 are his on Historic England's own list entries, and Cumberland Terrace of about 1827 is credited to Nash with J. Thomson. But Cornwall Terrace and Clarence Terrace are Decimus Burton's, the latter described as his work under Nash's supervision.

Two Burtons are involved and they are constantly confused. James Burton, 1761 to 1837, was the builder and principal financier and not an architect; he built Cornwall, Clarence and Chester Terraces and the eastern half of York Terrace, and funded Nash's park when the Crown would not. Decimus Burton, 1800 to 1881, was his son, and the architect. The claim that Decimus designed Cornwall Terrace as a teenager is simply arithmetic: he was born in September 1800 and the terrace was designed in 1821, which made him twenty or twenty-one.

The more useful warning is that Grade I listing here does not mean original fabric. The terraces were badly bombed, and the Gorell Report of 1947 set a reconstruction policy that in practice meant keeping the fronts and rebuilding behind them. In 1962 the London County Council refused the Crown's commissioners permission to demolish four terraces outright, and the minister conceded that some might have to be rebuilt behind replica façades. What followed:

• Clarence Terrace — Historic England's own list entry records it as completely reconstructed in 1965.
• York Terrace West — rebuilt behind the façades, the east end in facsimile, the rear elevation entirely new.
• Cumberland Terrace — substantially reconstructed behind its façade; the central and southern mews are post-war work by the Louis de Soissons Partnership.
• Cambridge Terrace — four of its ten houses were destroyed by fire, and the north end was rebuilt as offices in the 1980s.
• Chester Terrace — war-damaged, and restored in the 1960s.
• Park Crescent — rebuilt twice. The 1960s façade retention came to be regarded as badly done, and the crescent was rebuilt again to Nash's elevations, finishing in 2021.

Two of the villas are gone outright. Holford House was destroyed by a bomb in 1944 and demolished in 1948. Sommeries House was war-damaged and cleared, and Denys Lasdun's Royal College of Physicians of 1960 to 1964 stands on its site — the one deliberate break in the stucco, and the better for it.

The Inner Circle, and a date the Royal Parks gives two ways

The ground inside the Inner Circle, about seven hectares, was leased out for most of the nineteenth century: first to the Toxophilite Society from 1832, then to the Royal Botanic Society of London, which laid it out with lawns, a lake and a conservatory of 1845, in buildings by Decimus Burton. The lease expired in 1932 and the Society was dissolved the same year.

When the Society took the land is recorded wrongly in the statutory entry, which has it leased in 1838 to the "then newly formed" Society. The Society was founded in 1839, so it cannot have been newly formed the year before; the London Gardens Trust dates the lease to 1840, which is the figure to prefer.

On the reversion the gardens were redesigned by Duncan Campbell and named Queen Mary's Gardens, after the wife of George V. When they opened is given two ways by the Royal Parks itself: one of its pages says 1932, another says 1935, and its monuments page ties the opening to the Jubilee Gates, installed in 1935 for George V's Silver Jubilee. The defensible account is that the land reverted in 1932, the gardens were laid out between 1932 and 1934, and they opened under the name in 1935. The eastern gates were a gift from Sigismund Goetze in 1932.

The rose figures need the same care. The Royal Parks' garden page gives approximately eight thousand roses in eighty-five single-variety beds; its own history page gives forty thousand. The widely repeated "twelve thousand roses" and "eighty-five varieties" are not what either page says — a bed is not a variety. That this is London's largest collection of roses is the Royal Parks' own claim, and nothing independent supports it, so it is worth repeating only with the attribution attached. On timing the charity is more useful: the first two weeks of June.

One thing to avoid: the Inner Circle is not Nash's Great Circus, which was never built. The road belongs to the layout of 1811 to 1827, and no authority dates it more precisely than that.

The Open Air Theatre

The Regent's Park Open Air Theatre has stood inside the Inner Circle since 1932, and it is not run by the Royal Parks. It is an independent company, Regent's Park Theatre Ltd, registered charity 231670, with an auditorium of 1,304 seats, a season of about twenty weeks each summer, roughly 180,000 attendances a year, and no regular public subsidy. Drew McOnie has been artistic director since 2024 and James Pidgeon executive director since 2021.

The 2026 season ran from 2 May to 12 September. The 2027 season had not been announced by early November 2026, and since the 2026 programme was announced on 29 January 2026, late January is the pattern to watch. Separately, the Friends of Regent's Park put on a free Sunday music festival at the bandstand, which in 2026 ran every Sunday from 21 June to 20 September.

The lake, and the day the ice broke

The lake is Y-shaped, about eight hectares, with six islands, and it is shallow for a reason.

On 15 January 1867 some five hundred people were skating on it and about two thousand watching from the banks. The ice broke at around half past three in the afternoon. Forty people died — thirty-nine by drowning and one of hypothermia, on the verdicts returned by the inquest jury, which found accidental death in all forty cases before the coroner Edwin Lankester. Thirty-four bodies had been recovered by the following day. How many went into the water is not settled; accounts putting it at two hundred sit awkwardly with the evidence that nearly half of about five hundred skaters fell in.

What changed afterwards is the useful part. The jury recommended reducing the lake's depth, the First Commissioner of Works Lord John Manners agreed, and by June 1868 the lake had been drained, levelled, lined with concrete and cut to about four feet. That is the lake on the ground now. Swimming is prohibited in every Royal Parks lake.

Rowing boats and pedalos run from the boathouse at Hanover Gate from late March to October, with accessible boats and a crew hoist; there is a separate children's boating pond, added in 1930. York Bridge over the eastern arm is listed Grade II.

The birdlife is better than the park's reputation suggests. Grey herons have bred here since 1968, when they first nested on Heron Island, and the colony has spread since — at least fourteen pairs on Bandstand Island in a recent spring. Two hundred and fourteen species have been recorded in the park and about fifty breed inside it.

The bandstand

The bandstand is not original to the park. It is the Holme Green bandstand, moved here from Richmond Park in the 1970s.

On 20 July 1982 at 12.55pm an IRA bomb hidden beneath it exploded during a lunchtime concert by the Band of the 1st Battalion, Royal Green Jackets, who were playing music from Oliver! to an audience of about a hundred and twenty. Seven bandsmen were killed — six at once and a seventh on 1 August. The Royal Parks records twenty-four bandsmen injured and eight members of the public taken to hospital.

A small plaque on the base of the bandstand commemorates the seven, and survivors and families gather there for a memorial service each year. George Lloyd's Royal Parks for brass band, written in 1984, has a second movement, "In Memoriam", dedicated to them.

Four institutions inside the park

London Zoo is in the park rather than beside it. The Zoological Society of London took about eight hectares in the northern corner in 1828 and extended in 1905 and 1908, and the ground lies inside the registered boundary, with the zoo's listed buildings treated by the register as structures within the landscape. The register, incidentally, calls the owner the "Royal Zoological Society (founded in 1824)". It is the Zoological Society of London, and it was founded in 1826.

The London Central Mosque on the western edge exists because of a wartime decision. Churchill's War Cabinet authorised £100,000 towards a mosque for London's Muslims on 24 October 1940; George VI donated the site; the gift was accepted in 1944; and Egypt reciprocated with land in Cairo for All Saints' Cathedral. An open international competition in 1969 was won by Frederick Gibberd, building ran from 1974 and finished in July 1977 at a cost of £6.5 million. It holds 5,400 worshippers and was listed Grade II* in 2018.

Winfield House, on twelve acres inside the Outer Circle, has been the residence of the United States ambassador since 1955. It was built in 1936 for the Woolworth heiress Barbara Hutton, to designs by L. Rome Guthrie, on the site of Decimus Burton's Hertford Villa of 1825; it was listed Grade II in 2001; and its garden is the second largest private garden in London after Buckingham Palace's. The house was sold to the United States government for one dollar after wartime service as a barrage balloon site and an officers' club. The frequently repeated detail that it sits on a nine-hundred-and-ninety-nine-year lease has nothing behind it: the terms of the American interest in what is Crown land are not published.

Regent's University London occupies the old South Villa, on a Crown lease taken by Bedford College in 1908; the college moved in during 1911 and later merged away. Rockford College of Illinois took the lease in 1984 and founded Regent's College, whose first students arrived in 1985; degree-awarding powers came in 2012 and the present name in June 2013. Sussex Place, Nash's crescent of pointed turrets on the western side, is the London Business School.

Primrose Hill, which is not quite part of the park

The Royal Parks manages the two together as "The Regent's Park and Primrose Hill", which encourages the assumption that they are one place. They are two separately designated landscapes: Regent's Park is registered Grade I, Primrose Hill Grade II, under its own entry of 2 May 2001 covering twenty-five hectares. They are divided by the Outer Circle, Prince Albert Road and the Regent's Canal.

The hill became Crown property in 1841, bought from Eton College to extend the park; an Act of 1842 secured it as public open space, and the bridge linking it across the canal opened in 1843.

The view from the top is legally protected, which is why it has not been built out. Two protected vistas run from the Primrose Hill assessment point under the London View Management Framework: one to St Paul's Cathedral, with a viewing corridor 5,187 metres long, and one to the Palace of Westminster, at 5,112 metres. Directions made on 16 March 2012 require consultation with the Mayor before planning permission is granted for development that would intrude on either.

The hill's height is less certain than its view. Figures of about sixty-three to sixty-four metres circulate, but neither the Royal Parks nor Historic England states one, and the 68.3 metres often quoted is the framework's assessment point rather than the summit.

Hours differ from the main park. Primrose Hill is locked overnight through British Summer Time, from ten at night until six in the morning — in 2026 on Fridays, Saturdays and Sundays only, with a nightly closure around Bonfire Night, when fireworks, paper lanterns and gatherings were also prohibited.

Sport

The sports ground in the northern half of the park is substantial and routinely overstated. The Royal Parks' own brochure for the summer of 2026 gives thirty pitches and calls the site the largest outdoor sports facility in central London — not in London, and nothing like the hundred-and-more pitches sometimes claimed. The 2026 map numbered nineteen pitches plus eight for rounders and three for touch rugby.

Alongside them: twelve tennis courts, ten of them floodlit, a floodlit padel court, two netball courts, an outdoor table tennis table, and a 385-metre cinder running track. The pitches were relaid between 2002 and 2004, The Hub pavilion opened in 2005, and a hybrid turf pitch was added with a £380,000 grant from the Premier League, the Football Association and the Football Foundation.

Size, and a register entry to read carefully

Two areas are in circulation, and both are correct for what they measure. The Royal Parks manages about 166 hectares, or 410 acres, with a perimeter of roughly three and a third miles excluding Primrose Hill. Historic England's registered area is about 147 hectares, with Primrose Hill's twenty-five registered separately — which is where the 170-hectare figure comes from, by adding the two. The park has been registered Grade I since 1 October 1987. Together, Hyde Park and Kensington Gardens form the larger single expanse; Regent's Park is the more enclosed, and gives up its northern half to sport.

The register entry itself wants handling with care, which is unusual enough to be worth saying plainly. Its narrative was written in September 2000, amended in 2008 and given a minor amendment in August 2020, so it carries a recent date over a text a quarter of a century old. Four of its statements about listed structures are contradicted by the individual list entries it depends on:

• It calls the Mappin Terraces Grade I. They are Grade II.
• It dates the Giraffe and Hippopotamus House to 1830 or 1831. The list entry gives about 1836, by Decimus Burton.
• It has the Duke of Kent, whose statue stands at Park Crescent, dying in 1829. He died in January 1820, and the statue went up in 1824.
• It dates the ornate marble and granite drinking fountain near the zoo to 1896. It is 1869, by Robert Keirle — a date the Royal Parks gets right.

It also misnames and misdates the Zoological Society, and cannot decide whether the Society rented or acquired its land in 1828, saying both in the same document. None of this makes the designation less real. It does mean that a figure found only in that entry should be checked against the list entry underneath it before being repeated anywhere.

The park sits in the Regent's Park Conservation Area, which straddles two boroughs — Camden on the east side, Westminster on the west. Camden's half was designated on 1 July 1969 and extended in 1971, 1985 and 2011, with its appraisal adopted on 11 July 2011. The government's own planning dataset gives 1 November 1985 for the same area, which is a boundary-change date rather than a designation date.

Visiting

Pedestrian gates open at 5am and close at dusk, which moves through the year. The Royal Parks' summary box sometimes shows a single closing time, which is only that month's reading; the annual table is the thing to check. Vehicle gates run 7am to midnight.

The park is free to enter. The zoo, the Open Air Theatre, boating, the pitches and the courts are all charged for separately.

Regent's Park station is on the Bakerloo line, under the park's southern edge. Great Portland Street is on the Circle, Hammersmith and City, and Metropolitan lines — the Royal Parks lists only the Circle. Warren Street is on the Northern and Victoria lines, and Baker Street is the usual approach from the west. Euston and Marylebone are both under fifteen minutes' walk, from the east and the south-west respectively.

On step-free access the Royal Parks publishes nothing at all. The Open Air Theatre's own access page is more use: it states that Baker Street has no step-free access from platform to street level, names Euston as the nearest step-free station, and recommends the bus for anyone who needs it.

Dogs may be off the lead across most of the park but are excluded or restricted in the Avenue Gardens, the English Gardens, Queen Mary's Gardens, St John's Lodge Garden and around the boating lake. Cycling is allowed only where signed — the Broad Walk, the Inner Circle and Chester Road.
