NHER 4835 (Monument record) - Castle Cave 19th century folly

?Garden folly.
E. Rose.

2004. Visit.
Despite the name, there is no trace of a cave here now. The structure stands on a mound above the lakes and consists of a polygonal turret of flint with brick details and ornate pierced battlements. It has a ground floor fireplace and traces of a staircase. To the west is a polygonal single storey projection, with the angles squared off where it joins the tower, of flint with brick lancets. The original door to the west has been converted into a window at an early date and a south window made into a doorway. Another later door is beside that into the tower. Graffiti of the 1940s when estate was in military ownership. Derelict until recently, now a controlled ruin with a new viewing platform. The structure commands fine views and must date from after the construction of the South Lake in the mid 19th century, which would fit the design.
