I live in Linköping, Sweden.
In 1600 there were some executions on the main square which is somewhat ridiculously called a blood bath.
SAAB produces the SAAB Gripen fighter jet here.
The computer club at Linköping University, Lysator, put up the first web server in Sweden in February 1993, among the first 10–15 in the world.
The university's principal is named Mille Millnert.
The
roundabout dog originates from Linköping.
There is an IT and computer museum here. I also has an exhibition about gaming.
Linköping is one of few cities in Sweden that has a mayor.
yeah that's about it
