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:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
