The Castle of Coswig was mentioned first in 1187. There is no evidence for slav settlements before this date. In 1215 Coswig was attested as an "Oppidium". During this time it was one of the most important cities North of the river
Elbe. In the 16th century Coswig was already connected to a drinking water pipe from Wörpen. Weaving, pottery and farming played the most important role in economics. The city was nearly completely destroyed by Hispanic troops during the
Schmalkaldic War. The city belonged to the Principality of Anhalt-Zerbst from 1603 to 1793, to Anhalt-Bernburg until 1863, then to the Duchy of Anhalt until 1918. Until 1952, Coswig (Anhalt) belonged to the Free State of Anhalt, later the province of Saxony-Anhalt, from 1952 to the Halle district and from 1990 to the state of Saxony-Anhalt. In 1987 the city celebrated its 800th-year of existence. == Geography ==
