Construction of the Tui Cathedral began in 1120, but it was not consecrated until 1225 under the reign of Alfonso IX. It looks like a fortress because of its crenellated towers. Its structure is clearly Romanesque and later diverse decorative Gothic elements were added. From the Romanesque period there are the capitals that top the interior columns, and from the Gothic period there is the portico of the main entrance.
The main chapel located in the choir was completed in 1699 by Castro Canseco. The interior has a large prominent retablo de la Expectacion, and a large altar of relics in the Chapel of the Relics.
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.
