5 Oldest Buildings In The World That Are Still In Use

3. The Colosseum

Construction Year: 80 AD

Location: Rome, Italy

The Colosseum is the largest ancient amphitheatre ever built and is one of the oldest buildings in the world. It once regularly hosted more than 50,000 Romans, eager to witness reenactments of famous battles, dramas based on Roman mythology, and most importantly the blood and violence of the legendary gladiators. Unfortunately, the ruined state of the Colosseum today means that it can only host an audience of a few hundred people with temporary seating. However, on the upper floor of the outer wall there is now a museum dedicated to Eros, the god of love and sex in Greek mythology.
