On the Capitoline Hill, where has remained the seat of city's gouverment throughout the history, just few things remained unchanged by time going.
As archaeological find we can see the ruin of an old building once called insula that stay for apartment blocks. This tenement block of barrelvault construction is the only survivor in Rome from the imperial era.
In the south of the hill there are few traces of the temple of Jupiter, founded in honor of the arch-god around 590 B.C., it was the most important of ancient Rome.
The Rupe Tarpea (Tarpeian Rock) that we mention for its legendary importance is the southern tip of the Capitol.
