Train to Trier

After a few days relaxation in Koln, we hopped on another train and headed to Trier.

(Trains in Germany are great, by the way. Clean, fast, and affordable. I can't figure out why we can't do that here.)

Trier was a Roman city, and has many remnants of that history. One of the most obvious (and most impressive) is the Porta Nigra, or Black Gate. This huge gate was originally part of the city walls, but time (and opportunistic local rulers who used the walls as a stone quarry) have reduced the structure to just the gate.

Still very impressive! Here are a few picture of the Porta Nigra.
