Castle Coch is chiefly
known as a romantic folly supposedly reproducing
a small medieval Welsh chieftain's stronghold,
built in the 1870s, for the 3rd Marquess of Bute
to a design by William Burges, and possessing
the most remarkable interior decoration.
However, it was built upon the remains of a
genuine 13th century castle built in two stages.
Evidence was found of the building having been
deliberately slighted by mining.
