In the depths of this all-important hill, excavators say they they have found a cryptoporticus or underground passage that may have been the site at which the Roman Emperor Caligula was killed by the Praetorian Guard in January in 41 AD.
Excavation of the cryptoporticus began in September under the direction of archaeologist Maria Antonietta Tomei.
Another feature that with a large degree of certainty belongs to the original temple is a staircase connecting the temple-terrace to a cryptoporticus above the Lower Agora, between the terrace walls, or to the Lower Agora itself (total width of 2.15 m, preserved height 0.71 m).
a single large ambulacrum or "cryptoporticus in gamma", that is turned at right angles with its own staircase.
