Boarstall Tower was built by John de Haudlo in 1312, when King Edward II granted him a license to fortify his Mansion House of Boarstall with a wall of lime and stone.

It originally had a drawbridge, but this was removed when the building was upgraded in 1615, probably to a banqueting pavilion or a hunting lodge. The large arch over the doors (originally the gates), the bay window above it, the balustrading and frieze above, the other large windows, including the fine oriel windows at either end and the Jacobean chimneys all date from this time. In addition, the front turrets were lowered and some of the arrow loops were filled in.
