Genoa Cathedral is dedicated to Saint Lawrence (San Lorenzo), and is the seat of the Archbishop of Genoa. The cathedral was consecrated by Pope Gelasius II in 1118 and was built between the twelfth century and the fourteenth century as fundamentally a medieval building, with some later additions.
Various altars and chapels have been erected between the 14th and 15th centuries. The small loggia on the north-eastern tower of the façade was built in 1455; the opposite one, in Mannerist style, is from 1522. In 1550 the Perugian architect Galeazzo Alessi was commissioned by the city magistrates to plan the reconstruction of the entire building; however, he executed only the covering of the nave and aisles, the pavement, the dome and the apse.
The construction of the cathedral finished in the 17th century. The dome and the medieval parts were restored in 1894-1900.
The Museum of the Treasury lies under the cathedral and holds a collection of jewellery and silverware from 9 AD up to the present. Among the most important pieces are the sacred bowl brought by Guglielmo Embriaco after the conquest of Caesarea and supposed to be the chalice used by Christ during the Last Supper.

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.
