Chavenage House, Beverston, Gloucestershire is a country house dating from the late 16th century. The house was built in 1576 and is constructed of Cotswold stone, with a Cotswold stone tiled roof. David Verey and Alan Brooks, in their Gloucestershire Pevsner describe the house as "the ideal sixteenth-century Cotswold stone manor house". Chavenage is a Grade I listed building.
The estate of Chavenage was sold to Edward Stephens of Eastington in Gloucestershire in 1564. He built the house in the Elizabethan style, adding large windows to the south of the porch, much of the glass being obtained from redundant churches and monasteries in the area. On Edward's death, the estate passed to his son Richard and, on his death, to his second wife Anne, before his eldest son Nathaniel Stephens inherited it.
During the Civil War, Nathaniel Stephens raised troops and supported the Roundheads, and later became a member of Cromwell's parliament. Cromwell visited Chavenage House, and Stephens supported his planned regicide, and although he was not one of the signatories of Charles I's death warrant, he is nevertheless said to have died of remorse soon afterwards. It is also recounted that on the day of the Nathaniel's death, his ghost was seen leaving the house in a coach driven by a headless coachman dressed like the hapless king. The house is reputed to be one of the nation's most haunted homes
In 1944, the house was requisitioned and housed American troops prior to the Normandy landings in France.
