The museum is superimposed on the outer embankment walls that originally surrounded the arrow-shaped inner fort. In the resulting asymmetrical design, based on a pure 45-degree geometry, one side of the V-shaped building is cantilevered over the ruins. The intention is to merge the historic walls with the new building, acknowledging and continuing the rich history and use of the site. Access to the museum will be by footbridge over the fort's excavated moats.
