In Ancient Rome, the Forum was the centre of the Roman Empire. Until the 4th century AD, a thousand years of decisions affecting the future of Europe were made here. When Roman soldiers were out conquering the world in the name of the Emperors, temples, courts, markets, and government buildings were thriving in the Forum.
Located between two of Rome's famous hills, the Palatine and Capitoline Hills, it is now a collection of ruins having spent centuries as a quarry for marble and a cow paddock. The Forum became a very dense collection of buildings in its time but mostly all that remains today is columns, arches, and some scattered marbles so it can be difficult to make sense of it all. Ongoing archaeological work continues, and getting a map or a guide can really bring the bustle of the ancient site to life. You can get a great view over the Forum from the overlooking hills in the Farnese Gardens and from Michelangelo's Piazza del Campidoglio.
