[1] Coates Castle, a Grade-II mansion listed by English Heritage lies on land above the village in a position that affords extensive views across the Sussex countryside.

It was built in 1820 by John King in the Strawberry Hill gothic style and was extensively renovated in the early twenty-first century after years of gradual decline.

It consists of three blocks of land all within a one kilometre radius of Coates Castle which contain the only known British population of Gryllus campestris, a field cricket protected under Schedule 5 of the Wildlife and Countryside Act 1981.

The church is of early English style and consists of a single nave now covered by a wood floor with a bellcote (rebuilt 1961) and a small square chancel.

A small Sussex marble lead-lined font stands extant at the west end of the nave[7] and constructed within the south wall of the chancel is a sedile ( pl sedilia) or priest's chair.
