Porta Nigra (Black Gate)

The Porta Nigra, the Roman city gate, was built in the 2nd century AD. It was built of sand stone without mortar. Instead the stones were kept together with iron clamps. The name itself origins from medieval times and goes back to the black pollution patina on the gray sandstone.

The Porta Nigra is on the list of UNESCO's world heritage.

House of the Three Magi

The house has been built around 1230 when Trier's medieval city wall was not yet finished. As each house had to defend itself, it was accessible only by ladder or a wooden staircase that could be pulled up. The doors on street level are modern. Trier still has six such Romanesque residential towers, the Frankenturm being the oldest.

Main Market

The Main Market was the center of medieval Trier. There you can see

  • the Steipe, the city council's banqueting house
  • a reconstruction of the city yardstick
  • the pillary (a reconstruction, too)
  • access to the Cathedral
  • access to the Jewish quarter
  • access to six streets alltogether

It moved to this place from the river after the Viking destruction.

Trier Cathedral

The Cathedral stands on top of a former Constantinian Palace. The place was leveled in 330 and the palace was replaced by the largest Christian church in Antiquity, about four times as big as the present-day church. Today's Cathedral still contains a Roman central section with the original walls rising up to a height of 26 m (86 ft). The huge fragment of a granite column next to the entrance to the Cathedral is another indication of the Roman origin of the building. After destructions in the 5th and 9th centuries, the remaining nucleus was enlarged by Romanesque additions - today, the Cathedral, with its three crypts, its cloister, Cathedral Treasury, and Holy Robe Chapel, displays architecture and artwork from more than 1650 years.

The Cathedral is on the list of UNESCO's world heritage.
