It is shown on the Ordnance Survey First Edition 6-inch scale map, surveyed in 1846-1851 and appears to have held water until the late-1930s (Ordnance Survey 1853 and 1938).

NMR Information

Disused pond, still subject to seasonal flooding, and shown holding water on 19th-century maps. The pond appears to predate the boundary wall of The Retreat psychiatric hospital, built soon after 1839. Although not shown on late 18th- century maps, it could conceivably be of medieval date. It was probably used for watering livestock on Walmgate Stray.
