Trier, Germany 2020

The center of Trier is filled with old Roman buildings.
The Porta Nigra is one of a kind, the Römerbrücke has been crossing the Mosel River since the 2nd. century AD. A fantastic amphitheater that could accommodate 20.000 spectators in its days.
The Konstantin Basilika is one of the most spectacular churches I ever been in.
On the top of it, you get a statue of Karl Marx donated to the city by The Peoples Republic of China on Karls 200 years birthday in 2018.

You can get there from everywhere by train.
German railroad will get you there on time.
