Genoa part 2 :)

Here you can see Saint Laurence Cathedral and is the seat of the Archbishop of Genoa.

The cathedral was founded probably in the V or VI century AD, devoted to St. Sirus, bishop of Genoa. Excavations under the pavement and in the area in front of today’s façade have brought to light walls and pavements of Roman age as well as pre-Christian sarcophagi, suggesting the existence of a cemetery in the site. Later a church devoted to the Twelve Apostles was built, which was in turn flanked and replaced by a new cathedral dedicated to St. Lawrence martyr, in Romanesque style. Money came from the successful enterprises of the Genoese fleets in the Crusades.

The transferring of the cathedral favored the urbanization of the zone that, with the construction of it walls, in 1155, and the fusion of the three ancient city nuclei (castrum, civitas and burgus), became the heart of the city. The piazza, in absence of other public squares and centers of lay power, was the only city's public space for the whole Middle Ages. The cathedral was consecrated by Pope Gelasius II in 1118. Starting from 1133 the church had archiepiscopal rank. After the fire of 1296, provoked by fights between Guelphs and Ghibellines, the building was partly restored and partly rebuilt. Between 1307 and 1312 the façade was completed, the inner colonnades rebuilt with capitals and matronei added. The Romanesque structures remained pretty untouched, and frescoes of religious subject were also added.

Various altars and chapels have been erected between the XIV and XV the century. The small loggia on the northeastern 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 end in the XVII century. The dome and the medieval parts were restored in 1894-1900.
