The Palazzo della Cancelleria was the first palazzo in Rome to be erected from the ground up in the new Renaissance style. Its long facade engulfs the small Basilica di San Lorenzo in Damaso, the Cardinal's titular church, that is to its right, with the palatial front continuing straight across it. The entrance to the Basilica is on the right side of the facade. The 5th-century basilica (its interior has been rebuilt) sits, like the Basilica di San Clemente among others, on a pagan Roman mithraeum. Excavations beneath the "cortile" from 1988 to 1991 revealed the 4th- and 5th-century foundations of the grand Basilica di San Lorenzo in Damaso, founded by Pope Damasus I, and one of the most important early churches of Rome. A cemetery in use from the 8th century until shortly before the construction of the Palazzo was also identified.
