Castello delle Pietre, Medieval castle in Capua, Italy.

Castello delle Pietre takes its name from the large, regular limestone blocks of its lower two levels, traditionally taken from the Roman amphitheatre of Capua. The main wing runs along the street in an L shape, with a square keep projecting at the corner; its battlements and twin windows are a late 19th-century neo-Gothic rebuild. A late Gothic pointed portal frame (1380–1430) is set into the facade.

Prince Riccardo Quarrel Drengot built the fortress between 1062 and 1073 after gaining control of Capua through military conquest. The stronghold was constructed during this period as both a symbol of power and a defensive position for the ruling family.

The stone blocks in the walls come from Capua's Roman amphitheater, showing how medieval builders reused materials from earlier structures. You can still see these varied stones embedded throughout the masonry today.

The castle is managed by the Italian Ministry of Culture and has no regular opening hours for visitors. It is best to arrange a visit in advance by contacting the responsible authorities.

In 1191, the castle experienced a major siege when Riccardo d'Aquino attempted to capture the fortress held by Corrado di Lützelhardt. This event highlights the site's strategic importance in medieval power struggles.
