The collections of the Sinebrychoff Art Museum include some of the most valuable and internationally important paintings by old European masters to be found in Finland. The collections have mainly been made up of donations. The unique house museum of Paul and Fanny Sinebrychoff, a permanent exhibition on the 2nd floor makes up the core of the museum. The art collection of the Sinebrychoffs, including furniture and other artefacts was left to the Finnish government as a bequest in 1921.
