Køge, city, eastern Sjælland (Zealand), Denmark. The city lies on Køge Bay of The Sound (Øresund). First mentioned in the 11th century and chartered in 1288, it became a market centre and base for herring fisheries in the late 13th century. In 1677 Admiral Niels Juel won a great naval victory over the Swedes in the bay. Medieval remains include St. Nicholas Church (1324, rebuilt c. 1500), from the tower of which captured Wendish pirates (“Køge’s Chickens”) were hanged in the 14th century; the town hall (1570); and many old timbered houses (the oldest dates from 1527), one of which is the city museum. Industries include rubber and paint factories, sawmills, and chemical works. The land between Copenhagen and Køge is now an almost continuous strip of coastal suburbs. Pop. (2008 est.) 34,792; mun., 54,926.
