Caerphilly Castle/Castell Caerffili, Caerphilly, Wales

Gord and I spent the afternoon exploring Caerphilly Castle (Castell Caerffili), a 13th-century medieval fortress. Built by Gilbert de Clare around 1268, it was designed to control the region and resist Welsh attacks. 

It’s the largest castle in Wales and the second-largest in Britain, famous for its advanced concentric design (multiple rings of defensive walls) and extensive water defenses (moats and artificial lakes). 

The castle was damaged early in its history, later fell into decline, and was restored in the 19th–20th centuries.
