The wooden structure was replaced by more substantial buildings and a tall brick tower was added in 1475, protected by walls and a moat, and surrounded by an outer bailey.

The antiquary Edward John Rudge published a history, Illustrated and Historical Account of Buckden Palace, in 1839.

[1] The site is a scheduled monument and the great tower,[2] inner gatehouse[3] and curtain walls are Grade I listed buildings.

Initially it was used as a junior seminary carrying out the preliminary training of 11- to 18-year-olds aspiring to become Claretian Missionary priests or brothers.

The grounds, but not the buildings, of the Towers are open to visitors at all reasonable times but dogs are not permitted.
