Underground exploration like a must-see! "Church is composed of three layers"

This one is church near the Colosseum. Inside the great mosaic decoration. Photography is impossible Unfortunately, this church is not only that! Fact, it is a church that is made a total of three layers from the layer. Beautiful church, church remains of 4th century, the temple of Mithraism 2-3 century and dwellings of one century appears when you get off in the basement further whopping get off to underground mosaic decoration of the 12th century 1F! It seems to be something but matryoshka, temple in the dark basement is beautiful and it will surely be a good memories. You can hear the sound of water, the sound of running a large sewer Cloaca Maxima in the basement. By the way, it might be a little scary to one person who is small and dark. You stop by in passing the Colosseum tourism is also recommended ☆
