The story

Under the 18th-century garden of the Dukes of Osuna, Republican engineers dug 'Posición Jaca', the command bunker of General Miaja's Army of the Centre and his chief of staff Vicente Rojo, completed in August 1937. Some 15 m underground, it has a central gallery with rooms for about 200 people, generators, ventilation and gas-proof doors. It is one of the best-preserved Civil War command posts in Spain and shows how the defence of Madrid was run once the front had stabilised.

What you can see today

The restored underground galleries beneath the romantic garden of El Capricho.
