San Lorenzo is a Baroque-style Roman Catholic church building in Melfi. The octagonal church was initially built in the 1000s by the Byzantine rulers of the city, and was soon occupied by canons belonging to the nearby Abbey of Monticchio. In 1500, it became a parish church.
The church has suffered damage over the centuries from the earthquakes. The present portal and long stairs appears to date to the 17th century. The adjacent bell-tower, rebuilt in the 14th century by the family of Niccolo Acciaiuoli, has since collapsed, and only the base remains. In 2015, the church underwent refurbishment including demolishing a parish house built to the left of the entrance portal.
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.
