Prior Park Landscape Garden surrounding the Prior Park estate south of Bath, Somerset, England, was designed in the 18th century by the poet Alexander Pope and the landscape gardener Capability Brown, and is now owned by the National Trust. The garden was influential in defining the style known as the "English landscape garden" in continental Europe. The garden is Grade I listed in the Register of Historic Parks and Gardens of special historic interest in England. Around 1100 the site was part of a deer park set out by the Bishop of Bath and Wells John of Tours. In 1720s it was bought by Ralph Allen and landscaped to complement his new house. Further development was undertaken after the house became a seminary and then a Roman Catholic grammar school (which later became Prior Park College). In the 1990s of the park and pleasure grounds were acquired by the National Trust and a large scale restoration undertaken. Features of Prior Park Landscape Garden include a Palladian architecture bridge, lake and ancillary buildings. History Set in a small steep valley overlooking the city of Bath a park was established on the site by John of Tours, the Bishop of Bath and Wells, in around 1100 as a deer park. It was subsequently sold to Humphrey Colles, a lawyer and member of parliament for Somerset, and then another member of parliament, Matthew Colthurst. Even before the Dissolution of the Monasteries the walls which had enclosed the deer park had fallen into disrepair and the deer had escaped. The land was then returned to agricultural use. 18th-century design Purchased by the local entrepreneur and philanthropist Ralph Allen in the 1720s, Prior Park's English landscape garden was laid out with advice from the poet Alexander Pope during the construction of the house, overseen by Allen between the years 1734 and his death in 1764. During 1737, at least 55,200 trees, mostly elm and Scots pine, were planted, along the sides and top of the valley. The valley floor remained as grassland and drainage water was channelled to form fish ponds at the bottom of the valley. Later work, during the 1750s and 1760s, was undertaken by the landscape gardener Capability Brown; this included extending the gardens to the north, removing the central cascade and making the wooded hillside (combe) into a single sweep.
