The large amphithe­ater that housed 65000 spec­ta­tors in Roman days. Glad­i­a­tors bat­tled each oth­er as well as wild ani­mals in the Colos­se­um’s are­na, which is con­sid­ered one of the sev­en mod­ern won­ders of the world. In the giant ‘ruins’ of the Colos­se­um, you can vis­it the stands, the are­na and the under­ground spaces of the largest Roman amphithe­atre.
