Forts in Cologne

The Forts in Cologne form a system of military fortifications arranged in two concentric rings around the inner city, featuring towers, gates, and heavy walls made of stone and concrete. The outer ring road connects several preserved structures, allowing you to explore different sections of the complex in a day.

The Prussian administration began construction of these strategic fortifications in 1815, incorporating elements from earlier Roman and medieval defenses. The rings were designed to protect the city from military attacks and expanded over several decades.

Many former fortifications now function as event venues, parks, or sports facilities where residents spend leisure time. Some structures host exhibitions and guided tours where visitors learn more about construction methods and military use.

Visitors reach individual forts via the outer ring road, which links different sites together. Many installations are freely accessible, while some open only during guided tours or at specific times.

Fort V preserves documents and structural traces that show its transformation from a military base into a deportation facility during the Second World War. Visitors can see there how the function of a defensive structure changed drastically over time.
