Böttcherstraße is a street in the historic centre of Bremen, Germany. Only about 100 m (330 ft) long, it is famous for its unusual architecture and ranks among the city's main cultural landmarks and visitor attractions. Most of its buildings were erected between 1922 and 1931, primarily as a result of the initiative of Ludwig Roselius, a Bremen-based coffee-trader, who charged Bernhard Hoetger with the artistic supervision over the project. The street and its buildings are a rare example of an architectural ensemble belonging to a variant of the expressionist style. Several of the houses can be classed as Brick Expressionism. Since 1973, the ensemble has been protected by the monument protection act.
