During the 1941 Battle of Roupel, the fortress held out for three days against the German 18th Mountain Corps until the Greek command ordered a surrender following the collapse of the wider front.
The fortifications were part of a larger defensive project known as the Metaxas Line, named after the Prime Minister of Greece who oversaw its construction.
The complex includes over 6 kilometers of underground tunnels, though only specific sections are open to the public.
Roupel was one of the few Greek positions that successfully repelled enemy infantry attacks during the Axis invasion.
The museum grounds feature a dedicated memorial dedicated to the soldiers who fought at the fort.
The site is still under the jurisdiction of the Greek military, which facilitates the guided tours.
Several cannons from the WWII era are still positioned in their original exterior concrete emplacements.
Fort Roupel is a strategic defensive complex located on the Greek-Bulgarian border, best known for its critical role during the German invasion of Greece in April 1941. The fortress consists of an extensive network of underground tunnels and combat galleries carved into the mountain. Visitors can explore the internal museum, which documents the 'Battle of Roupel' where Greek forces maintained their positions despite heavy bombardment. The site serves as a monument to the Metaxas Line, a system of bunkers and fortifications built in the late 1930s. Guided tours provide access to sections of the subterranean passages where soldiers lived and operated artillery. The location remains an active military installation managed by the Hellenic Army. Displays feature original uniforms, weaponry, and historical photographs from the mid-20th century. The site offers panoramic views of the Strymon River valley and the surrounding border landscape.
