Porta Nuova is a monumental city gate of Palermo. It represents the entrance of the Cassaro (the main and most ancient street of the city) from Corso Calatafimi (the way to Monreale) and is located beside Palazzo dei Normanni, royal palace of Palermo.
According to the historian Tommaso Fazello the original gate was built in the 15th century. After the Charles V's conquest of Tunis, the Emperor came to Sicily. He entered in Palermo through this gate on 5 September 1535. In order to commemorate this event, the Senate of Palermo decreed to rebuild the gate in a more sumptuous style. The Viceroy of Sicily Marcantonio Colonna set off the construction in 1583. The gate was completed in 1584.
The gate was destroyed in 1667 because of a fire erupted inside the warehouse of the building. The Senate of Palermo commissioned the architect Gaspare Guercio to rebuild the gate. The work was completed in 1669.
The facade leading to the Cassaro has the typical style of the triumphal arches. The facade leading to the Corso Calatifimi and Piazza Indipendenza presents four big telamones depicting the Moors defeated by Charles V.
References: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.
