The Palace of the Tarquins?

Italian archaeologists have uncovered a sixth-century BC Etruscan palace at Gabii 12 miles outside of Rome. One of their finds was an image of a minotaur, which the Tarquins -- Rome's Etruscan kings -- used as an emblem. The palace was destroyed in about 510 BC, which might have something to do with the revolt that led to the founding of the Roman Republic.

Maybe.
