Fort di Capo Passero is located on a small island Isola di Capo Passero. It was commissioned in 1599 by the crown of Spain. Developed by Giovanni Antonio del Nobile, a German-sicilian architect, the fort was built to combat the dangers of severe and violent pirate activity in the Mediterranean region. Throughout the years, the fort remained a highly sought after naval resource as it was the guardian of the entrance to Europe. Whoever controlled the fort was considered to control the entrance to Europe.
During the 18th century the fort was used as a military prison. However on December 30, 1866 a Royal Decree halted military prison activity in the fort. In 1871 a lighthouse was built in the terrace of the fort, which was operated by the Italian Navy until it was fully decommissioned in the late 1950s.
References:The Chapel of St. Martin is the only completely preserved Romanesque building in Vyšehrad and one of the oldest in Prague. In was built around 1100 in the eastern part of the fortified outer ward. Between 1100 and 1300, the Rotrunda was surrounded by a cemetery. The building survived the Hussite Wars and was used as the municipal prison of the Town of the Vyšehrad Hill.
During the Thirty Years’ War, it was used as gunpowder storage, from 1700 to 1750, it was renovated and reconsecrated. In 1784, the chapel was closed passed to the military management which kept using it as a warehouseand a cannon-amunition manufacturing facility. In 1841, it was meant to be demolished to give way to the construction of a new road through Vyšehrad. Eventually, only the original western entrance was walled up and replaced with a new one in the sountren side. The dilapidating Rotunda subsequently served as a shelter for the poor.
