Lupercal

The Lupercal (from Latin lupa "female wolf") was a cave at the southwest foot of the Palatine Hill in Rome, located somewhere between the temple of Magna Mater and the Sant'Anastasia al Palatino.

Luperci, the priests of Faunus, celebrated certain ceremonies of the Lupercalia at the cave, from the earliest days of the City until at least 494 AD.

In January 2007, Italian archaeologist Irene Iacopi announced that she had probably found the legendary cave beneath the remains of Emperor Augustus's house, the Domus Livia, on the Palatine.

[2][3] On 20 November 2007, the first set of photos were released showing the vault of the grotto which is encrusted with colourful mosaics, pumice stones and seashells.

The current scholarly consensus is that the grotto is not the Lupercal and that the cave was located lower southwest, closer to piazza Sant'Anastasia al Palatino.
