Køge (Danish pronunciation: [ˈkʰøː(j)ə], older spelling Kjøge) is a seaport on the coast of Køge Bugt (Bay of Køge) 39 km southwest of Copenhagen. It is the principal town and seat of Køge Municipality, Region Sjælland, Denmark. In 2023, the urban area had a population of 38,588.
Køge is located in the Copenhagen metropolitan area and is connected to downtown Copenhagen by the E line of the S-train commuter rail system. Køge is also on the Copenhagen-Ringsted Line that was opened in June 2019. The new line positioned Køge as a central hub in Denmark's transport system.
Like most Danish cities, the origins of Køge precede written history. Køge was first recognized as an official market town in 1288, as a contrast to the ecclesiastical center at that time – Roskilde – and was an important merchant town during the late Middle Ages.
During the local witchhunt, called Køge Huskors (1608–1615), at least 15 people were convicted of witchcraft and burned at the stake. Køge suffered during the wars between Denmark and Sweden (1643–1720, → Battle of Køge Bay). In 1807, the town and surrounding area was the scene of the Battle of Køge between British and Danish troops. Køge remained a small town until the late 19th century, when industrial development and population growth began. Today, Køge forms the core of the 18th most populous urban area in Denmark.
The port is directly connected with the Scandinavian Transport Centre, a large business park on the northwestern outskirts of Køge, where – among others – the headquarters and the Danish distribution centre of the multinational, Danish-founded, discount supermarket chain Netto is located.
Køge Museum is located at 4 Nørregade in a preserved former merchant's house from the year 1619. Further down the street, in No. 29, lies KØS Museum of art in public spaces. It is the only art museum in Denmark dedicated specifically to sketches and models for art works in the public realm. Among its holdings is the original model for The Little Mermaid in Copenhagen.
The historical architecture of the town centre is one of the major attractions of Køge. The oldest dated half-timbered house in Denmark, which is also the oldest dated non-nobility and non-religious building of the nordic countries, can be found in Køge. It was built in 1527. Originally a section of a row of hovels, it is now a part of the public library. Pictures can be found in the gallery. The Third largest Viking Ring Fortress was found near the city of Køge, Denmark.
Near the house is Sankt Nicolai Church. The tower of the church contains a lighthouse, which was the first to be built in Denmark.
Køge Town Hall dates from 1552 and is the oldest town hall in Denmark still in use as such.
Køge Torv, the market square, is, with an area of almost 1 hectare (2.5 acres), the largest town square in Denmark outside Copenhagen and the largest and best-preserved medieval town square in Denmark. There are fair days on the square Wednesday and Saturday.
Kjøge Miniby  (Kjøge Mini-Town) is a historically correct model of the town from the year 1865 – built to a scale of 1:10.
The football club HB Køge was created through a merger of professional football between Herfølge Boldklub and Køge Boldklub in 2009. It currently plays in the Danish 1st Division. Their home ground is Køge Sports Park (Capelli Sport Stadium).
