Cadw's description

Located at the end of the breakwater at the SE extremity of Llanddwyn Island.

Probably built late C18, the predecessor to the larger, more visible Twr Mawr (Llanddwyn Lighthouse) which was erected early C19 (probably between 1800 and 1823).

Circular day-mark tower, built as a landmark for shipping. Built of local rubble, with tapering walls and saucer dome; large square headed doorway at base.

A good surviving example of a late C18 day-mark, and part of a group with the lighthouse, keepers' and pilots cottages nearby.
