History+
Knole was first mentioned in documents in 1281. The name of the estate likely derives from its location on a hill. Initially owned by Geoffrey, Lord de Say, it was sold in 1456 to Thomas Bourchier, the Archbishop of Canterbury, who had Knole expanded into a fortified palace between 1456 and 1486. In 1538, the estate passed into the possession of Henry VIII, who began further expansions in 1543.
