The Roman amphitheatre in Trier — another symbol of the ancient period in the history of the city, striking evidence of the power of the Roman Empire. The amphitheater is located outside the medieval city centre, a mile from the Market square, on the hillside of Petrisberg.

The construction of the amphitheater was conducted simultaneously with the construction of the Roman city wall in the first century of our era. Its arena is an oval with a length of 75 and a width of 50 m, around which are arranged three-tiered spectator stands. 26 rows could accommodate 20 thousand spectators, ready to enjoy the brutal gladiatorial games, battles with wild animals and mass executions. Like a Roman Coliseum, under the arena Trier amphitheater was a large basement, where expected to fight gladiators and exotic animals. With the help of special platforms and a complex system of lifts achieved their spectacular appearance in the arena right out of the ground. In its original purpose amphitheatre lasted until the fifth century.

In the middle ages the Roman amphitheatre was partially destroyed, its land part was the place of stone extraction for urban construction. Extant buildings in 1986, as the other ancient buildings in Trier, were taken under the protection of UNESCO.

Currently the Roman amphitheatre is the venue for various events, concerts and the annual Festival of antiquity (historical reconstruction of the Roman gladiatorial fights).
