Gate in Trier
Porta Nigra
The best-preserved Roman city gate north of the Alps stands in dark sandstone at the entrance to Trier’s pedestrian zone. Viewing it from outside is free and impressive enough on its own. Entering the interior costs a modest fee and reveals the full scale of 2nd-century Roman engineering.
