San Lorenzo in Damaso is a parish and titular church in central Rome. It is incorporated into the papal Palazzo della Cancelleria. Archaeological evidence suggests the site, like those of many churches in Rome, may have formerly housed a pagan temple. The first documentary evidence of a church at this site dates from AD 499. According to tradition, in the AD 380s a basilica church was erected by Pope Damasus I in his own residence.
The original basilica was demolished by Cardinal Raffaele Riario, a nephew of Pope Sixtus IV who commissioned the imposing Renaissance-style Palazzo della Cancelleria (1489–1513). The palace was built of spolia and stone from nearby ancient Roman buildings, including the Colosseum, and enveloped the new basilica of San Lorenzo in Damaso under the right wing.
The interior decoration was begun by commissions of the resident of the Palace, Cardinal Alessandro Farnese, in the late 16th century. Cavaliere d'Arpino painted the walls of the right counter-facade. The main altar hosts the painting of Saints and Coronation of St. Mary by Federico Zuccari. Below the altar are the relics of Pope St. Eutychian and Pope St. Damasus I.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
