Built in 1280, this castle has a fascinating life story. It is the second largest castle and grounds in UK, slightly smaller than Windsor castle. The water defenses are now home to plenty of birds and the grounds offer fantastic views of this stunning castle

A small summit above Risca. Known locally as the "Twmp" (the hump), the pimple or the nipple, due to the shape of the mound on the summit.
