The Porta Nigra (Latin for black gate) is a large Roman city gate in Trier, Germany. It is today the largest Roman city gate north of the Alps and has been designated a World Heritage Site.
The name Porta Nigra originated in the Middle Ages due to the darkened color of its stone; the original Roman name has not been preserved. Locals commonly refer to the Porta Nigra simply as Porta.
