The Roman Forum in Rome

There's a fine 8 euro offer for visiting the Roman Forum, Palatine Hill and Colosseum. The forum was the Roman political, religious and commercial center, used for the meetings of the Senate and public ceremonies. In the 4th century, together with the decline of the whole empire, ruin started to stick its claws into the forum, and 900 years of construction efforts sank. The area was even exploited in the Middle Ages for its stone and marble. Anyway, the Lapis Niger (black marble stone covering Romulus' grave), the Curia, meeting place of the Senate, and Tempio di Antonina e Faustina are worth a visit.
