kilkenny Castle shot from the rose garden.

is a castle  built in 1195 by william marshall to control a fording-point of the river nore and the junction of several routeways. It was a symbol of Norman occupation and in its original thirteenth-century condition it would have formed an important element of the defences of the town with four large circular corner towers and a massive ditch, part of which can still be seen today on the Parade.
