Trier, founded in 16 B.C. as “Augusta Treverorum”, is the oldest town in Germany. The quantity and the structural quality of the surviving monuments – the bridge, the remains of the town’s fortifications, thermal baths, amphitheatre and warehouses – make Trier an outstanding testimony to the four centuries of the Roman era. These Roman buildings and the subsequent Christian buildings that rose from their ruins – and are now inseparable from them – were inscribed together in the World Heritage List in 1986.

Trier is directly and tangibly connected to one of the most important events in human history: Constantine’s campaign against Maxentius in the year 312, which led to the recognition of Christianity as the state religion of the Roman Empire in the Edict of Milan in 313.
