Alatri is a small, unassuming town in the Lazio region of Italy, but it is home to one of the country’s most mysterious and fascinating ancient sites. The town’s well-preserved Roman amphitheatre is one of the largest in Italy, and it is still used for performances today. The amphitheatre is built into the side of a hill, and its semicircular shape and multiple levels give a great view of the surrounding countryside. The theatre is also home to a number of subterranean tunnels and caves, which are said to be haunted by the ghosts of the gladiators who once fought here.
