San Felipe Castle is a defensive construction in a predominantly Neoclassical style. The first castle was built during the reign of Felipe II and it was redesigned between 1731-1775. It is one of the most representative examples of the major 'fortified batteries' of the 18th century. It was used to defend the Ferrol tidal inlet and for land offensives. The castle has a system of protruding walls, covering the flanks of the lateral walls. It follows the academic model of its time - the Enlightenment - in this case, through the application of mathematics to the art of war. It has a geometric layout and stonework. It was designed by the military engineers Francisco Montaigú, Juan de la Ferriére and Juan Vergel.
There are magnificent views from the castle, particularly for the tidal inlet and the A Palma castle. The building was recently acquired by Ferrol Council and will be renovated and refurbished for cultural use.
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.
