Castello Normanno
Founded by the Lombards, this castle became very important under the Normans, when it was the head of a powerful county; there did King Roger II stay and there he held the Assizes of Ariano and coined the ducat. Later the castle was remodeled by the Angevins and the Aragonese. All around the castle there is a wide and panoramic public park.
On a cliff overlooking the Irpinian valleys, it used to be a hospital. Thereabouts were many ancient majolica furnaces, and nowadays the building houses a permanent exhibition of majolica art.
Home of the European Centre for Norman Studies, and the Archaeological, Civic & Ceramics Museum. The town has a long, ancient history and is still a center of ceramics manufacturing.
It is a majestic building that in 18th century was converted into a high-school complex. Today it houses the museum of Norman civilization.
