Pembroke Castle

Pembroke Castle has a long and fascinating history, for it was around 1093 that Arnulf de Montgomery built the small inner bailey standing at the end of the promontory. Only a few years later the castle withstood a long siege by the Welsh, although its defenders were near starvation. The late 12th century keep is both an outstanding feature and architectural novelty, for it has a massive cylindrical tower with an unusual stone dome.
