Montuenga Castle in Soria, Spain forms part of the defensive line of the Jalón River set in a natural passage between the plateau and strategic basin of the Ebro. The area was subject to disputes, notable during the Castilian Civil War.
The castle is perched on a high hill, steep and long, from which it dominates the town of Montuenga de Soria. The remains of the building, two polygonal towers at each end, are joined by walls.
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.
