Avebury Manor & Garden is a National Trust property consisting of a Grade I-listed early-16th-century manor house and its surrounding garden. It is located in Avebury, near Marlborough, Wiltshire, England, in the centre of the village next to St James’s Church and close to the Avebury neolithic henge monument.
The manor house was built on or near the site of a Benedictine cell or priory of St Georges de Boscherville, founded in 1114.Subsequently the site passed into the ownership of Fotheringhay College in 1411. Fragments of the religious foundation were incorporated into the later house.
William Sharington bought and surveyed the manor in 1548 suggesting alterations to the existing building. The earliest parts of the present house were probably built after William Dunch of Little Wittenham in Berkshire (now Oxfordshire) purchased the estate in 1551. It was some way from most of his lands which centred on Wittenham, but he appears to have purchased it because of an interest in ancient monuments such as the Avebury Stone Circles. Around that time a stone dovecote was erected in the grounds. In the 1580s, William Dunch passed it on to his younger son, Walter Dunch, whose daughter, Deborah, Lady Moody, grew up at the manor before emigrating to America and founding Gravesend in Brooklyn in 1645. Walter Dunch’s widow, Deborah, subsequently married Sir James Mervyn (who served as High Sheriff of Wiltshire in 1596), and the couple were responsible for a major extension or remodelling of the house around 1601. In 1640 the Dunch family sold it to John Stawell and then, in 1652 to George Long before Stawells return from the Tower of London.
