Western Europe

Going back into the early Middle Ages, a wall defined an area surrounding the Cathedral, the close, whose center today comprises, along with the Cathedral, the recently redesigned Cathedral Square with the grandiose view onto the Romanesque west façade of the Cathedral and the Early Gothic Church of Our Lady. http://www.trier-info.de/english/cathedral-square-info

The Electoral Palace directly next to the Basilika is considered one of the most beautiful rococo palaces in the world. http://www.trier-info.de/english/electoral-palace-info

For the newly arrived guest, the Porta Nigra is the best place to begin a tour of Trier. The gate dates back to a time (about A.D. 180) when the Romans often erected public buildings of huge stone blocks (here, the biggest weigh up to six metric tons). http://www.trier-info.de/english/porta-nigra-info
