Mithraeum under the Basilica of S. Lorenzo

In 1938 a Mithraeum was found 3.45 mtrs under the Basilica of S. Lorenzo in Damaso, in a cellar near the Sacrament's Chapel. In the 15th cent. this Basilica was incorporated in the Palazzo della Cancelleria.

Of the sanctuary, situated near the entrance of the Palazzo, to the right along the facade, only some remnants have been preserved: a fragment of a wall; traces of a white mosaic floor probably of the central aisle (Br. 1.50), laying between the two side-benches. On a fragment of a wall, traces of red painting decorated with small crescents and stars have been found.
