Description
The Teahouse and Grotto in the grounds of St Ann's Hill House is an 18th-century ornamental garden building, noted for its charm. It is a rectangular structure with two storeys and one window, constructed with flints and featuring a parapet. Each long side has two ogival-headed open arches that lead into a grotto-like chamber, which is paved with pebbles, brick, and bones arranged in a geometric pattern. The walls are adorned with shells and spar, and the ceiling is supported by pillars that mimic stalactites made of felspar and tufa. To the right of the building, there is a curved staircase with a wooden handrail designed in a chinoiserie style, leading to the upper room, which has one casement window set in a round-headed opening. The structure was recently damaged at the time of the survey.
