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 Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
