The Free Hanseatic City of Bremen is the smallest of Germany's 16 states. A more informal name, but used in some official contexts, is Land Bremen.
The state of Bremen consists of two separated enclaves: Bremen, officially the 'City' (Stadtgemeinde Bremen) which is the state capital, and the city of Bremerhaven (Stadt Bremerhaven). Both are located on the River Weser; Bremerhaven is further downstream and serves as a North Sea harbour (the name means "Bremen's harbour"). Both cities are completely surrounded by the neighbouring State of Lower Saxony (Niedersachsen). The two cities are the only administrative subdivisions the state has.
