Audley's Castle is a three-storey tower house named after its 16th century owner, John Audley.
There are thousands of small stone towers similar to Audley's Castle in the Irish countryside. They are one of the commonest of archaeological sites, which indicates these were not buildings put up for the higher aristocracy, but for lesser lords and gentry. Most were built in the late Middle Ages (roughly 1350–1550). Audley's was built towards the end of this period.
There is very little historical information about the buildings in the small courtyard around Audley's. Only a minority of towers had courtyard walls at all, and their buildings were clearly less important than the tower. The towers in different parts of the country vary, with distinct regional patterns. Audley's with its two turrets linked by an arch is one of a type found in County Down only.
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
