This is one of the most fascinating churches in Rome, built on a number of different levels that expose the long history of religious practice that took place here. Over the centuries, the site housed a succession of churches and temples, each new building covering the remains of its predecessor. Three of these can still be seen in this architectural patchwork, and it is believed that even more structures lie in the ground beneath. Behind the 18th century facade are the remnants of a church built in the 12th century, embellished with beautiful mosaics. The second level still shows traces of a church that stood here in the 4th century, and the final level unveils yet another long buried treasure - the ruins of a house that once served as a temple dedicated to the pagan god Mitra.
