Køge is also on a new rail line under construction between Copenhagen and Ringsted, and due for completion in 2018.
The new line will make Køge a central hub in Denmark's transport system.
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.
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. Originally a section of a row of hovels, it is now a part of the public library. The Third largest Viking Ring Fortress was found near the city of Køge, Denmark. The tower of the church contains a lighthouse, the first to be built in Denmark.
