Remnantz is a country house in Marlow in Buckinghamshire. It is listed Grade II* on the National Heritage List for England.
The main house was built around 1720 and was occupied by the Royal Military Academy, a facility conceived by Colonel John Le Marchant for training potential junior officers aged 13 to 18, from the Academy's formation in May 1802[1] until it moved to Sandhurst as the Junior Department of the Royal Military College, in 1811.[2] A stable block, located a short distance south-east of the house, was built around that time.[3] The house was acquired by Thomas Wethered, a brewer, in the first half of the 19th century and it was occupied by Lieutenant Commander Owen Wethered, High Sheriff of Buckinghamshire, in the 1960s. The family business was Thomas Wethered & Sons Ltd, a brewery which operated in Marlow from 1758[4] until it closed in 1988.[5] Remnantz has been owned by the Bosley family since 2007.[6]
