Rauceby and Kesteven County Asylum, is a now-defunct mental institution in the parish of Quarrington, Lincolnshire. Building work was commenced in 1897, the facility was completed and opened in 1902. After changing hands and names several times the main hospital building was closed in 1998 and abandoned for several years.
From 2004 parts of the site underwent redevelopment to convert it into private housing.
The hospital buildings included a chapel (now deconsecrated), two graveyards, a mortuary and various tunnels connecting wards.
