Amos Rex Art Museum, Helsinki

Amos Rex, which originated from the Amos Anderson Art Museum established in 1965 and named after the publisher and art supporter Amos Anderson, is known for its focus on modern Finnish art from the 20th to the 21st centuries.

In 2013, the museum announced its plan to construct a new underground extension beneath Lasipalatsi Square, close to its main site on Yrjönkatu, utilizing both the underground space and the Lasipalatsi building's above-ground facilities. The design was crafted by JKMM Architects, known for their work on the Turku Main Library and the Finnish pavilion at the 2010 Shanghai World Expo.

This new development represented a fascinating blend of historical and contemporary elements. Situated under Lasipalatsi square, the modern structure, featuring entrance areas, offices, and the Bio Rex cinema, aimed to introduce a sculptural aesthetic of the new century to the site, echoing the square's 1930s appearance.

Construction kicked off in January 2016, and by August 2018, the complex was open to the public. The design, highlighted by vaulted domes, allowed for a spacious, pillar-free interior. These domes, made of on-site cast reinforced concrete, were not only structurally efficient but also added versatility to the space. Skylights were strategically placed to frame views of nearby landmarks, like the central chimney, connecting the underground museum to the cityscape.

The Amos Anderson Art Museum mainly features artworks from the 20th century, including some of the earliest pieces from Amos Anderson's collection. Among its notable paintings are works by artists such as Francesco Bassano, Paul Signac, Louis Valtat, Roger Fry, Alfred Finch, Ragnar Ekelund, Magnus Enckell, Eero Nelimarkka, Tyko Sallinen, Tove Jansson, and the Swedish painter Palm. The museum focuses on acquiring contemporary art for its collections.
