Description
The structure is a small tower made of red sandstone rubble, originally built with a square plan and a battlemented top, although the southeast corner has collapsed. On the north side, there is a pointed door with a brick head at ground level, and to the left, a large flight of rubble stone steps leads up to a first-floor opening that is missing its lintel. There is a small lancet window on the west side and a blocked lancet window on the east side, both at ground level. The south side of the tower has also collapsed.
