Roman Monuments, Cathedral of St Peter and Church of Our Lady in Trier

The Roman Monuments, Cathedral of St. Peter and Church of Our Lady in Trier are buildings and monuments of particular historical importance in Trier, Germany, that were together listed as a UNESCO World Heritage Site in 1986. These sites demonstrate the political, economic, and historical importance of Trier during the Roman Empire as one of the four capital during the Tetrarchy period, and as a prominent city during the early days of the Holy Roman Empire in the Middle Ages. From UNESCO/CLT/WHC:

"Trier is an example of a large Roman capital after the division of the empire. The remains of the Imperial Palace, in addition to the Aula Palatina and the Imperial Thermae, are impressive in their dimensions. The city bears exceptional testimony to Roman civilization owing to the density and the quality of the monuments preserved: the bridge, the remains of the fortified wall, thermae, amphitheatre, storehouses, etc. In particular, funerary art and the craftsmanship of potters, glassworkers, and moneyers flourished in the city."

In 2009, the site was featured on a golden 100-Euro coin.
