The Katyn Museum, a branch of the Polish Army Museum in Warsaw, moved to its new headquarters in the Warsaw Citadel in 2015. Its new space was designed by BBGK Architects: Jan Belina-Brzozowski & Konrad Grabowiecki and Jerzy Kalina & Krzysztof Lang, along with their team.
In 2017, the Katyn Museum was named a finalist for the Mies van der Rohe Award.
