Wilster was granted town rights under Lübeck law in 1282, and thereby counts itself among Schleswig-Holstein's oldest towns. Wilster forms the centre of the Wilstermarsch, a major cattle raising area in Germany.
On 1 July 2005, the town administration and the Amt of Wilstermarsch merged into one authority.
The Old Town Hall built in 1585 is among Schleswig-Holstein's finest preserved Renaissance buildings.
