Roman Monuments, Cathedral of St Peter and Church of Our Lady in Trier
Trier, which stands on the Moselle River, was a
Roman colony from the 1st century AD and then a great trading centre
beginning in the next century. It became one of the capitals of the
Tetrarchy at the end of the 3rd century, when it was known as the
‘second Rome’. The number and quality of the surviving monuments are an
outstanding testimony to Roman civilization.
