Description
The Round House is an early 19th-century building, likely originally a toll house. It is a half-octagonal structure with one storey, finished in stucco and topped with a polygonal slate roof. Each face features one pointed window, and there is a porch with a pointed doorway. The building was relocated to its current site after road widening works in 1988.
