The amphitheater's cellar, known as the 'hypogeum', includes a central shaft for a mechanical lift system used to bring animals and gladiators onto the arena floor.
Construction required removing part of a Roman wall circuit, indicating the arena was integrated into the city’s defense system.
The structure was built during the reign of Emperor Trajan, reflecting the growing importance of the Roman city Augusta Treverorum.
The arena floor area measures approximately 75 by 50 meters.
During the Middle Ages, the structure served as a source of building material for nearby construction projects.
Excavations in the late 19th century uncovered the complex subterranean chambers that were previously filled with debris.
The amphitheater is part of the 'Roman Monuments, Cathedral of St. Peter and Church of Our Lady in Trier' UNESCO site.
The Trier Amphitheater is a UNESCO World Heritage site constructed around 100 AD, utilizing a natural hillside to support its tiered seating. It once accommodated approximately 18,000 spectators for gladiatorial contests and animal hunts. The structure features a unique cellar system located beneath the arena floor, originally used for scenery and animal transport. Unlike many Roman amphitheaters, it was built directly into a slope, which significantly reduced the amount of masonry required for the exterior walls. It remains one of the best-preserved Roman amphitheaters in Germany. The venue transitioned through various uses throughout history, including serving as a medieval quarry and a vineyard site. Today, the grassy arena floor serves as a public space while the surrounding stone tiers remain accessible for walking.
