Sbarramento Lodrino-Osogna, Military fortification complex in Riviera District, Switzerland
The Lodrino-Osogna fortification consists of 23 infantry bunkers forming a V-shaped barrier across the Ticino Valley between mountain slopes.
Construction of this defensive system started in 1939 and finished in 1943, incorporating road barriers and railway mining installations during World War II.
The fortification name LONA combines the first letters of Lodrino and final letters of Osogna, reflecting local naming conventions for military structures.
The complex includes multiple artillery positions along the Mairano-Mondascia line, with bunkers strategically positioned to control access to Alpine passes.
A military airfield built in 1940 at Lodrino complemented the fortification system, enabling both air combat operations and ground troop support.
