The church of Saint Clement. Over: the beautiful and restored frescos of Masolino da Panicale and the 12 th cent. mosaics of the apse.
Under: two layer of history. The older church built in the fourth century and dedicated to San Clemente, the third pope after St Peter and underneath it again, the roman buildings which are, themselves, made up of different "strati".
In front: when you look in front of you, at the alter, beware and listen....under the very ancient basilica of Saint Clement there is a small underwater river that has a little waterfall! Onetime they were both visible but in late, for reasons of prudence, they were hidden by a wall through which one can still today distinctly hear the noise of running water. Don't forget...always over, in front and under!
