Basilica di San Clemente, Rome

A visit to Basilica di San Clemente is a fascinating journey through time. From the upper basilica, which dates from the beginning of the 12th Century and whose apse boasts the mosaic The Triumph of the Cross, one passes into the 4th-century lower basilica, and, via a stairway, down to the roman constructions and to the mitreo, a 3rd-century temple dedicated to the God Mithra. Of particular interest are the frescoes in the chapel of St Catherine, painted between 1428 and 1431 by Masolino da Panicale, possibly with the collaboration of Masaccio.
