The Chedworth Roman Villa is a Roman villa located at Chedworth, Gloucestershire, England. It is one of the largest Roman villas in Britain. The villa was built in phases from the early 2nd century to the 4th century, with the 4th century construction transforming the building into an elite dwelling arranged around three sides of a courtyard. The 4th century building included a heated and furnished west wing containing a dining-room (triclinium) with a fine mosaic floor, as well as two separate bathing suites – one for damp-heat and one for dry-heat. The villa was discovered in 1864, and it was excavated and put on display soon afterwards. It was acquired in 1924 by the National Trust who have conducted a long-term conservation programme, with new on-site facilities and cover-buildings.
