Porta Nigra - Trier

The Porta Nigra in Trier is one of the most impressive Roman structures north of the Alps and has been on the UNESCO World Heritage List since 1986. The structure is approximately 29 metres high , 36 metres wide and 21 metres deep .

Built around 170 AD , this imposing city gate served as the northern entrance to the then Augusta Treverorum , today's Trier.

The Porta Nigra is constructed from massive sandstone blocks (some weighing up to 6 tons!) , stacked without cement and connected with iron staples. In the Middle Ages, many of these staples were removed to reuse the metal, resulting in the traces of rust that are still visible today. The blocks were brought to the construction site by ox carts from a local quarry north of Trier.

Originally the building had a light colour, but over the centuries weathering and environmental influences turned it dark, leading to the name "Porta Nigra" or "Black Gate".

In the 11th century, the Porta Nigra was converted into the Church of St. Simeon , in honor of the hermit Simeon who lived in the ruins of the gate. After his death in 1035, he was canonized and buried in the gate. In 1804, Napoleon Bonaparte ordered the church to be dismantled and the structure to be restored to its original Roman form.

One of the most popular tours is "The Secret of the Porta Nigra" , where a guide in the role of a Roman centurion takes visitors on an interactive journey through the history of the monument. This tour is suitable for visitors aged 10 and over and is conducted in German.
