Trier is a city in Germany on the banks of the Moselle River. It is the oldest city in Germany, founded before 16 BC. Trier sits in a hollow midway along the Moselle valley, with the most significant part of the city on the east bank of the river. Vineyard-covered slopes stretch up to the Hunsrück plateaux in the South and the Eifel in the North. The border with the Grand-Duchy of Luxembourg is about 15 km distant.
