Porta Nigra

Porta Nigra

Porta Nigra, also known as the "Black Gate," is located in Trier, Rhineland-Palatinate, Germany. It is a Roman gate and a symbol of the city of Trier. The Porta Nigra is the best-preserved Roman city gate north of the Alps. In 1986, it was designated as a UNESCO World Heritage Site along with other Roman ruins and the cathedral of Trier.

The name "Black Gate" originated in the Middle Ages. The gate, built from gray sandstone, darkened over time due to weathering. Originally constructed around 180 AD, it served as the northern gate of Augusta Treverorum (present-day Trier), a city of the Celtic Treveri tribe. The ancient Romans favored constructing buildings with large cubic blocks. The largest stone block in the Porta Nigra weighs six tons. Sandstone blocks mined nearby were cut using bronze saws and stacked without mortar, with horizontal stones secured using iron clamps.

As a symbol of Trier, the Porta Nigra has frequently appeared on German postage stamps. It first featured on an Imperial German stamp in 1940. In 1947 and 1948, it appeared twice more as a symbol of the Rhineland-Palatinate state. On the occasion of Trier’s 2000th anniversary in 1984, Deutsche Bundespost issued a special 80-pfennig stamp featuring the Porta Nigra. In 2002, a 1-euro definitive stamp of the gate was also released.
