Description
The Grotto at Mill Bank is a folly located in a landscaped park, dating from the mid to late 18th century. It was likely built for Sir Henry Conway, who lived at Park Place from 1751 to 1795. The structure is made of knapped flint, shells, tiles, and flint nodules. It features a small hemispherical flint form built into the bank, with a semi-circular open front. The arch's extrados is created by large flint nodules. Inside, the dome is lined with square knapped flints, and there are ribs of large shells that rise to a geometric pattern of square and small round flints at the apex. Surrounding the base of the alcove is a semi-circular seat made of knapped flint, topped with tiles. The floor displays a lozenge pattern of knapped flints.
