Limestor Rainau-Dalkingen

Since 2005, the complex, which was developed into a triumphal gate under Emperor Caracalla, has been a UNESCO World Heritage Site together with the entire Roman border fortifications and is part of the open-air museum on the Rhaetian Limes established in 1972, which also includes the nearby fort Buch and its civilian settlement. The gate is surrounded by an imposing glass protective structure.
