Palacio de Viana was established as the family estate in 1492 by Gómez Suárez de Figuroea. He died childless and was succeeded by his nephew. The original house has experienced numerous alterations up to our days, of which we can highlight the extension in the 17th century, which gave it its current appearance to a great extent.
The palace covers a surface of more than 6,500 square metres, of which almost 4,000 of them correspond to courtyards, gardens and open spaces. Visitors, more than 70,000 every year, are especially attracted by the elegant patios and the superb 18th century garden of this palace which has lately become a museum, thanks to the collaboration of an important institution in the town.
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.
