The remains of a mile of walls are what's left of one of the largest Roman villas in England, beautifully set in a wooded valley on the eastern fringe of the Cotswolds. Thirty-two rooms, including two complete bath suites, have been identified, and covered walkways take you over the colorful mosaics, some of the most complete in England. Audio guides are available, and there's a small museum. Look out for the rare large snails, fattened on milk and herbs during Roman times, in the grounds; they come out on warm, wet days. There's a café here, but it's also an ideal place for a picnic. Look carefully for the signs for the villa: from Bibury, go across A429 to Yanworth and Chedworth. The villa is also signposted from A40. Roads are narrow. The site is 6 miles northwest of Bibury and 10 miles southeast of Cheltenham.
