Polish Army Museum, Warsaw

Architect WXCA has added a low-lying extension with coloured- concrete walls to the Polish Army Museum, part of the Warsaw Citadel.

The in-situ concrete’s pink hue draws on the red brick of the Citadel, a 19th-century former barracks. In order to break up the monumentality of the 7.5m-high walls, some of the concrete was cast with a military-inspired chevron pattern created using rubber moulds.
