An impressive reminder of Trier's Roman past, this edifice is now the city's major Protestant church. This structure was built by the emperor Constantine around AD 310 as the imperial throne room of the palace. At 239 feet long, 93 feet wide, and 108 feet high, it demonstrates the astounding ambition of its Roman builders and the sophistication of their building techniques. The basilica is one of the two largest Roman interiors in existence (the other is the Pantheon in Rome). Look up at the deeply coffered ceiling; more than any other part of the building, it conveys the opulence of the original structure. An ornate rococo garden now separates the basilica from the Landesmuseum.
