Plan of Caerphilly Castledetails

This is one of the largest, the most imposing, and the most scientifically constructed castles in all Wales. It must also have been one of the most striking in situation, so long as its great lake encircled it, and its vast towers seemed to rise directly from the water. But the draining of the lake in modern times [1930s] has much impaired the picture, as the vast ruins now rise from a dead flat of marshy meadow ground.” (p. 176)
