 During the Interregnum, the castle was restored to use, due to concerns about a potential Royalist invasion, but was abandoned as obsolete after the restoration of Charles II to the throne.By the time that Alexander Pope visited in 1734, the castle was overgrown and in ruins.William Chamberlayne inherited the castle in 1826 and built a crenellated tower on the south-east end of the property the following year, inspired by a proposal by the antiquarian Horace Walpole that the castle be made habitable.
