Spandau (ˈʃpandaʊ̯) is the westernmost of the 12 boroughs (Bezirke) of Berlin, situated at the confluence of the Havel and Spree rivers and extending along the western bank of the Havel. It is the smallest borough by population, but the fourth largest by land area.
Modern industries in Spandau include metalworking, and chemical and electrical factories. BMW Motorrad's Spandau factory made all BMW's motorcycles from 1969 until final assembly plants were added in Rayong, Thailand, in 2000, and Manaus, Brazil, in 2016.
Rathaus Spandau, Spandau's seat of government, was built in 1913. Other landmarks include the Renaissance-era Spandau Citadel, the 1848 St. Marien am Behnitz Catholic church designed by August Soller, and Spandau arsenal. That arsenal's Spandau machine gun inspired the slang Spandau Ballet to describe dying soldiers on barbed wire during the First World War, and later was applied to the appearance of Nazi war criminals at Spandau Prison. In 1979, the English New Romantic band Spandau Ballet again re-purposed the term for its name.
The history of Spandau begins in the 7th century or 8th century, when the Slav Heveller first settled in the area and later built a fortress there. It was conquered in 928 by the German King Henry I, but returned to Slavic rule after the rebellion of 983.
In 1156, the Ascanian Earl Albrecht von Ballenstedt ("Albrecht the Bear") took possession of the region. 1197 marked the first mention as Spandowe in a deed of Otto II, Margrave of Brandenburg – thus forty years earlier than the Cölln part of medieval Berlin. Spandau was given city rights in 1232.
During Ascanian rule the construction of Spandau Citadel began, which was completed between 1559 and 1594 by Joachim II of Brandenburg. In 1558 the village of Gatow became part of Spandau. In 1634, during the Thirty Years' War, Spandau was surrendered to the Swedes.
In 1806, after the Battle of Jena and Auerstedt, French troops under Napoleon took possession of the city and stayed there until 1807.
