Description

The Caverna del Dio Mithra is a small cave known to man for many thousand years. It was the place of a Mithras temple during the times of the Roman Empire. During excavations two Mithras reliefs were discovered.

The cave starts with a huge pit, an entrance doline with a diameter of six meters. A small stair was cut into the south-western wall leading down to the floor of the cave. The cave itself is a huge-domed chamber, about six meters wide and twelve meters long.

The temple consisted of an altar at the far end, with a Mithras relief. Two parallel stone benches provided seats for the believers. It is typical for the Mithras cult to worship underground, either in natural or artificial caves. Later, when the Romans became Christians, the cult was practised secretly in this cave. Finally, the cave was forgotten and rediscovered by chance in 1963.
