Castel Capuano

Castel Capuano is a castle in Naples, southern Italy. It takes its name from the fact that it was at that point in the city walls where the road led out to the city of Capua. The castle is at the southwest end of via dei Tribunali, and until recently housed the Naples Hall of Justice, which has now moved to the new Civic Center, the Centro Direzionale.

The structure was built in the 12th century by William I, the son of Roger II of Sicily, the first monarch of the Kingdom of Naples. It was expanded by Frederick II of Hohenstaufen and became one of his royal palaces. On 19 August 1432, Sergianni Caracciolo was stabbed by four knights in the service of the Queen in his room in Castel Capuano.
