One of the most beautiful places to visit in Nocera Inferiore is the medieval castle. Strategically located on the top of Santa Andrea's hill, this fortified structure was founded in the 9th century. In 1138 it was destroyed by the troops of Ruggero II. Helena, the widow of Manfred of Sicily, was imprisoned in the Castle and died here after the battle of Benevento (1268).
Of the Castle you can still see the two walls, the Gothic arches of the aviary and the apse area of the church of Santa Maria alla Torre, located behind the keep. Of particular beauty is the Royal Cavallerizza divided into spans and covered by barrel vaults. Currently the Castle is in the management of the Municipality of Nocera Inferiore after the homonymous Palace has been established inside it.
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.
