The Royal Botanic Society was a learned society founded in 1839 by James de Carle Sowerby under a royal charter to the Duke of Norfolk and others. Its purpose was to promote "botany in all its branches, and its applications." Soon after it was established, it leased the grounds within the Inner Circle in Regent's Park, London, about 18 acres (7.3 ha), for use as an experimental garden. Sowerby remained as secretary for some 30 years, and J. B. Sowerby and W. Sowerby later also served as secretaries. The garden was open to members and their guests and also to the general public for a fee on certain days of the week. It included large palm-houses and a water-lily house. In the summer, flowershows, fetes, and other entertainments were held there.In 1932 it failed to secure a renewal of the lease, and the Society was dissolved. Its surviving record were deposited in the St. Marylebone Public Library.The site became Queen Mary's Gardens, which is run by the Royal Parks Agency, and is fully open to the general public without charge as part of Regent's Park.

The Readymoney Drinking Fountain, also occasionally known as the Parsee Fountain, is a Grade II listed structure near the middle of the Broad Walk footpath on the east side of Regent's Park, in London. It lies southeast of London Zoo, close to the highest point of Regent's Park, about 41 metres (135 ft) above sea level, in an area with few trees, making it widely visible across the park. The drinking fountain was erected in 1869, with the £1,400 cost funded by Sir Cowasji Jehangir Readymoney, a successful Parsee businessman and philanthropist from Bombay, as a token of thanks to the people of England for their protection of the Parsees in British India. The structure was built to the Gothic design of Robert Keirle, who was the architect of the Metropolitan Drinking Fountain and Cattle Trough Association. It was constructed by the sculptor Henry Ross, using 10 tons of white marble from Sicily, and 4 tons of pink and grey granite from Aberdeen. The main four-sided structure rests on three octagonal steps. The central white marble block has a pink granite basin on each side, with granite standing blocks on the ground beside each basin. Small apertures were included at the base of the central block to allow dogs to drink. Above each basin is a carved marble panel, with one depicting a lion and another a Brahmin bull, topped by a frieze decorated with inlaid stars and a triangular pediment resembling a gable. The central block rises to a gabled spire with a decorative terminal, with three pink granite columnettes rising to a single pinnacle at each corner. Three of the gables have a carved bust, depicting Readymoney, Prince Albert, and Queen Victoria, and the fourth has a clock. The drinking fountain was unveiled on 1 August 1869 by Princess Mary of Teck; she was a granddaughter of George III, and her daughter later became Queen Mary. It was listed at Grade II in 1970, and it was restored in 1999–2000 with over £400,000 of funding from the Heritage Lottery Fund. A modern plaque above the basin on the south face of the fountain reads: "This fountain erected by the Metropolitan Drinking Fountain and Cattle Trough Association was the gift of Sir Cowasjee Jehangir (Companion of the Star of India), a wealthy Parsee gentleman of Bombay, as a token of gratitude to the people of England for the protection enjoyed by him and his Parsee fellow countrymen under the British rule in India. Inaugurated by H.R.H. Princess Mary, Duchess of Teck, 1869. Restoration supported by the Heritage Lottery Fund 1999 – 2000.Further restoration work was undertaken in 2016 and 2017. The water no longer runs, but a modern drinking fountain has been installed nearby.

Constructed in 1934, Historic England describe it as "a key symbol of British (and International) Modern Movement architecture". The pool housed the zoo's collection of penguins for 70 years. Changing attitudes to keeping animals in captivity, and concerns regarding the suitability of the structure for penguin well-being, saw the pool's closure in 2004 and its subsequent replacement by Penguin Beach.

Regent's Park (officially The Regent's Park) is one of the Royal Parks of London. It occupies high ground in north-west Inner London, administratively split between the City of Westminster and the Borough of Camden (and historically between Marylebone and Saint Pancras parishes). In addition to its large central parkland and ornamental lake, it contains various structures and organizations both public and private, generally on its periphery, including Regent's University and London Zoo. What is now Regent's Park came into possession of the Crown upon the dissolution of the monasteries in the 1500s, and was used for hunting and tenant farming. In the early 1800s, the Prince Regent proposed turning it into a pleasure garden. The Park was designed by John Nash and James and Decimus Burton. Its construction was financed privately by James after the Crown Estate rescinded its pledge to do so, and included development on the periphery of townhouses and expensive terrace dwellings. The park is Grade I listed on the Register of Historic Parks and Gardens.
