Linköping is a city in southern Sweden, with a population of 94,298 (SCB 2001). It is the seat of Linköping Municipality with 136,000 inhabitants.
Linköping is the center of an old cultural region and celebrated its 700th anniversary in 1987. Nowadays Linköping is most well known for its university and its high-technology industry. Dominating the city's skyline from a far distance is the tower of the cathedral.
The city is situated south of lake Roxen (which is part of the historically important water paths Motala ström and the Göta Canal) where the main road from Stockholm to Helsingborg crosses the river Stångån (and Kinda kanal).
This road was part of the Eriksgata route that the newly elected king had to travel according to medieval Swedish Law. In the 20th century road system, it was first called Riksettan (national highway no 1). It is currently called E4 and has been redirected to pass outside the city on the north side. Further contributing to Linköping's excellent communications is its situation on the main southern railway line connecting Stockholm with Malmö and Danish capital Copenhagen. There is also a minor airport.
