The Porta Nigra is a large Roman city gate located in Trier, Germany. It is the best-preserved Roman city gate north of the Alps and is considered one of the city's most iconic landmarks. The name "Porta Nigra" means "Black Gate" in Latin, referring to the dark color of the stone used in its construction. The gate was built in the 2nd century AD and served as an entrance to the city of Augusta Treverorum, as Trier was known in Roman times. Today, the Porta Nigra is a UNESCO World Heritage site and a popular tourist attraction. **
