A long single-storey pavilion next to the Centennial Hall, designed in 1913 by Hans Poelzig as a temporary exhibition building and reconstructed in 2016 as a permanent gallery. The Four Domes Pavilion now houses the National Museum's collection of Polish post-war modern art — Magdalena Abakanowicz's monumental fibre sculptures, Tadeusz Kantor's installations, and a deep collection of Polish posters and graphic design.
The pavilion alone is worth the trip to the Centennial Hall grounds; combine with the Centennial Hall, the Japanese Garden and the Multimedia Fountain for a full afternoon east of the centre.
