The Doria Castle of Portovenere is a proper example of Genoese military architecture, even though it has undergone some structural modifications due to the progress of fortifications and firearms. When you first glance at Castello Doria, it looks like one solid piece. But it actually consists of two distinct parts positioned at different levels and enclosed in large Cyclopean walls.
The exact date of construction of the first fortified building is still unknown. Historic documents mention it for the first time in 1139, when the Republic of Genoa took control of the hamlet of Porto Venere. The current castle was built on the remains of the more ancient structure in 1161.
In the 13th century, the castle was at the center of the battles between Genoa and Pisa. It ended up under Nicolò Fieschi’s large fief, to eventually return under the control of the Republic of Genoa in 1276. Major reconstruction works took place between the 15th and 17th centuries, to modernize the castle according to the military and architectonic criteria of the time. At the beginning of the 19th century, during the French rule under Napoleon Bonaparte, the Castello Doria was used as a prison.
Today, this ancient fortress belongs to the Municipality of Portovenere. It underwent a series of accurate restoration works in the 1970s. Apart from welcoming hundreds of visitors for some historic sightseeing and panoramic views of the Bay of Poets, it is also a venue that hosts cultural events, art exhibitions and weddings.

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.
