The Focke Museum is the museum of history and the history of art for the city and state of Bremen. It was formed in 1924 by the merger of a museum of industry and commerce and the previous historical museum, and is named for the founder of the latter, Johann Focke (1848–1922), a Bremen privy councillor (German: Senatssyndikus) and father of Henrich Focke. It is located in 4.5 hectares (11 acres) of grounds in the Riensberg neighbourhood of the city. In addition to a main building which opened in 1964 and was extended in 2002, the museum complex includes buildings dating from the 16th to the 19th centuries.
