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 city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
