Second day at the cistern! Today we continued to clean the cistern. Now the limits are all visible, except for the western part, where there are trees which probably caused part of the collapse of the structure. We also entered inside the cistern.
From the inside, we saw that the walls are made of square stone blocks, while the roof of the cistern is made up of a very thick layer of cocciopesto.
Our goal is to finish cleaning the structure and understand how it was built.
