Porta Nigra
The Porta Nigra is a large Roman city gate in Trier, Germany, formed of two projecting semicircular towers flanking paired arched gateways. Constructed of grey sandstone after 170 AD, it served as the northern entrance to Roman Trier and later underwent medieval conversion into a church before being restored toward its Roman form.

What Porta Nigra looked like in its prime.
A massive grey-sandstone Roman gate composed of two near-semicircular, multi-storey towers linked by a central corps de logis with paired arched carriageways at ground level. Rows of stacked arched openings and blind arcading puncture the façades; a crowning cornice and parapet run along the roofline. The gate sits directly beside a wide street lined on the southern approach by a remnant colonnade. Stone surfaces are weathered and patched but the overall blocky, ashlar masonry and layered arcades define the silhouette.
