The Castillo Palacio de Marcilla is a Gothic-style castle built in the 15th century by Mosén Pierres de Peralta. At first it had a defensive character but when the Marquisate of Falces was instituted it became the residential palace of the Marquises. The gateway to the castle, which houses the drawbridge under which the moat runs, is next to what is considered to be the Homage Tower, one of the four towers that make up the corners of the castle. Inside the fortress there was a large parade ground around which the rooms and rooms were distributed. The palace chapel preserves its 16th century paintings.
Acquired by the Government of Navarra in 1976 and thoroughly restored in the 2008-2012 period, it currently houses the town hall and other municipal bodies.
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.
