The park at Addington Palace is the traditional site of a hunting lodge, but there is no evidence to suggest that one existed here prior to the present park being laid out. (PastScape 404111 at map ref TQ37046414)
Eastward from Croiden standeth Addington, now the habitation of Sir Oliff Leigh, wherby is to be seene the ruble of a Castle of Sir Robert Aguilon, and from him of the Lords Bardolph, who held certaine lands here in fee by Serjainty to find in the Kings Kitchen at the coronation one to make a dainty dish which they called mapigernoun and dilgerunt. What that was I leave to the skillfull in ancient Cookerie, and returne to the river. (Camden)
Sir Robert Aguillon, had a licence to fortify and embattle his manor house at Addington
A spot of ground near the church, being still called the Castle Hill, serves to ascertain the site of this mansion, which, most probably, continued to be the manerial residence till the year 1400, when the manor house, which was pulled down about twelve years ago, (and which was situated at the foot of the hill,) was erected; as appears by the following inscription which was over the door: In fourteen hundred and none, Here was neither stick nor stone, In fourteen hundred and three The goodly building which you see. This house was built chiefly of flint, mixed with chalk, and very strongly cemented. (Lysons)
