Description
The Sopwell Nunnery ruins are the unroofed remains of a large, two-storey mansion built in the mid-16th century by Sir Richard Lee, incorporating parts of the original Sopwell Nunnery. The east face features three-light Perpendicular mullioned windows that have been partly blocked or extended during the rebuilding. The walls are constructed of flint with brick headers and dressings, along with a moulded stone string. There are various other foundations and parts of buildings on the site, which are now much overgrown. To the west, there was a large building in the field that has been modernised and subsequently demolished, but medieval foundations remain visible.
