Which Roman site is located in Trier, Germany?

Augusta Treverorum is the ancient Roman name for the city of Trier, which is known to be one of the oldest cities in Germany. Established around 16 BC, it served as a significant Roman administrative center and a hub of trade. Trier is notable for its well-preserved Roman architecture, including the Porta Nigra, an impressive city gate that is a UNESCO World Heritage site, as well as the Imperial Basilica and the Roman Amphitheater. The identification of Augusta Treverorum with Trier highlights the city's rich Roman heritage and significance in Roman history. While the Colosseum is a famous amphitheater located in Rome, the other names mentioned—Aquincum (located in modern-day Hungary) and Arausio (now known as Orange in France)—are not associated with Trier.
