Description

The sham ruin located in the garden to the west of Denton House is likely from the early 19th century. It is a small structure that has further decayed over time, now roofless with only two walls still standing. The walls are made of flint and include medieval moulded stone details. In the east wall, there is a small 15th or 16th century, four-centred arch traceried window, although the mullions are missing.
