The sewage pipe
The sewer winds under the surface of the road useful to an area wider than that found, beyond the perimeter of the church. That maintenance was done through a small well which was still visible. Two sections of the pipe with a vault cover and consist of different techniques can be observed: one is dug into the rock and the other has walls covered with bricks and the base in clay-brick. It is assumed that a pipe is older that the other or that they were made by different workers. They were clogged by mud poured in at one moment (perhaps a flood) holding everyday objects carried by the water. These date the last use of the pipe to the VII century. Lithic manholes had to be placed on the wells.
