These buttresses, too, are topped with crocketed pinnacles at the castellated roofline. The parapet of the nave is also castellated. The roof line is castellated, the battlements purely for ornament, not defence. It is castellated and turreted in parts.

From 1757, the Duke began construction of an enormous castellated mansion at Douglas. "One of the most amazing of 19th Century castellated mansions". Other early castellated buildings in Wales were Gwrych Castle in Flintshire. Castle Peak takes its name from its castellated summit. Waugh also paid for the construction of a new pier, adorned with castellated watch towers. The castellated tower permits excellent views of the coastline, town and river. The west wall of the hall is castellated and probably early nineteenth century.
