The Moated Manor at Otford Palace was already well established by the time that Thomas Bourchier, Archbishop of Canterbury, enlarged a small manor house at Knole (in Sevenoaks about 6.5km south of Otford) between 1456 and 1486.
Knole was one of the two palaces (Otford was the other) seized by Henry VIII from Thomas Cranmer in 1537. Henry found it to be a good home for his daughter – later to become Mary I – during his divorce from her mother, Catherine of Aragon.
