Bath House, Reservoir and Conduit South South West of Heythrop House

The Bath House, reservoir, and linking conduit located south-southwest of Heythrop House were built in the early 18th century, likely around 1710, by Thomas Archer for the Duke of Shrewsbury. This small, square, single-cell building is constructed of dressed stone and ashlar, featuring dressed stone quoins, a corbelled stone roof with a gabled front and hipped back, and large oculi on the southwest and southeast sides. The northwest side is blind, while there is a plain doorway on the northeast side. Inside, the walls are lined with ashlar, and the oculi have segmental rear-arches and deep cills that create seating. To the northeast, there is a small reservoir, polygonally kite-shaped in plan, also lined with ashlar and fed by a spring. A conduit runs from this reservoir, under a garden path, to the bath house. The bath house, reservoir, and nearby screen are significant features in this early example of a naturalistic garden.
