Simple 16th century tower house with drop hole at roof level to defend the door. It is said to have been built on the site of an earth work castle built by John de Courcy in the late 12th century, and was an important mensal manor of the Earls of Ulster.

Immediately below the castle is a natural landing place known as Seneschal's Port, which was probably named for one of the Savages who held the post in the 15th century, and who in all probability built the castle.

Directions: Near Strangford Harbour, in the village.
