The city of Soria formed in a valley near the castle that defended the Douro Riverbanks on the border between the Crowns of Aragon and Castile. The city was destroyed towards the end of the 12th century when Sancho of Navarre attacked it, therefore a great defensive wall was built to prevent further destruction. The wall defended a surface of 100 hectares that went from the Douro River up to the pastureland known as “La Dehesa”, and also from the castle up to the hill where you can find the Chapel of El Mirón.
The Sorian wall was destroyed by General Durán at the end of the Spanish Independence War to avoid French troops from entrenching in the castle. This is the reason why there are so few remains of this castle and why we can only see part of the tower and some parts of the defensive walls. From the castle, you can see a 360º view of the city and the bridge that crosses the Douro River, and in the Chapel of San Saturio, you can see frescos depicting the castle as it once was.
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.
