Trier, the oldest city in Germany, has been called "Roma Secunda", the second Rome, and is full of Roman monuments.

Established in the 1st century B.C.E., Trier was the capital of the West-Roman Empire until the 5th century and still boasts a number of preserved Roman sites including the Porta Nigra, the basilica and an amphitheater which seated 30,000.
