Construction of the Ciudad Rodrigo Cathedral began in the 12th century and did not finish until the 14th century. The architecture of the cathedral is uniform, despite later reforms and additions that can be seen in some of the chapels, such as the San Blas chapel.
The Portico del Perdón alone contains more than 400 Romanesque and Gothic sculptures of great beauty. Although it began in the 12th century, the work continued to the 15th, meaning that its style shows a clear transition from Romanesque to Gothic, as well as the Neoclassic tower.
One of the principal attractions is the impressive Gothic vault. The choir should not be forgotten either, strangely it has no religious motifs instead is decorated with fauna and flora images. The cloister is wonderful and is where the contrast between the two styles of architecture is best noted.
Another jewel, the impressive Portico del Perdon is compared by some to the Catedral de Santiago de Competela. During the War of Independence this part of the building was fired at by Napoleonic troops and has the impacts of cannon fire on it.
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.
