ROME – Archaeologists on Tuesday unveiled an underground grotto believed to have been revered by ancient Romans as the place where a wolf nursed the city’s legendary founder Romulus and his twin brother Remus.

Decorated with seashells and colored marble, the vaulted sanctuary is buried 52 feet inside the Palatine hill, the palatial center of power in imperial Rome, the archaeologists said at a news conference.

The archaeologists are convinced that they have found the place of worship where Romans believed a she-wolf suckled Romulus and Remus, the twin sons of the god of war Mars who were abandoned in a basket and left adrift on the Tiber.

Thanks to the wolf, a symbol of Rome to this day, the twins survived, and Romulus founded the city, becoming its first king after killing Remus in a power struggle.

Ancient texts say the grotto known as the “Lupercale” – from “lupa,” Latin for she-wolf – was near the palace of Augustus, Rome’s first emperor, who was said to have restored it, and was decorated with a white eagle.

That symbol of the Roman Empire was found atop the sanctuary’s vault, which lies just below the ruins of the palace built by Augustus, said Irene Iacopi, the archaeologist in charge of the Palatine and the nearby Roman Forum.
