Kilkenny Castle was built in 1195. It was surrounded by a deep moat, fragments of which are still visible. Both the castle and the gardens as well as the adjacent park are open to the public. In the castle, you can see part of the collection of the National Gallery of Art and the Butler Gallery located in the basement, in which periodically changing exhibitions are organized. One of the four towers, known as The Parade Tower, has been converted into a conference center.
It was originally an Anglo-Norman stone castle, created for William Marshall, 4th Earl of Pembroke. It was a symbol of the Norman occupation, and at the same time was an important defensive element of the city. It changed hands several times in the following centuries, until Arthur, the 6th Marquis of Ormonde, handed it over to the people of Kilkenny in 1967 for a nominal fee of £ 50.
