Dublin is a schizophrenic city, where you can find historic buildings right next to modern ones. No building personifies this better than Dublin Castle, which can't make up its mind. It has parts from the medieval ages, the 18th century, and the 20th century. The castle has long been an important place for the government in Dublin and is designed accordingly. The interior is famous for its decoration, including its Waterford crystal chandeliers. An impressive landmark, the Dublin Castle is a jewel of the great city of Dublin.
