Kongsvinger Fortress (Norwegian: Kongsvinger festning) is located in the city of Kongsvinger which is located within Kongsvinger Municipality in Innlandet county, Norway. It is situated on a hill west and north of the Glomma river, standing astride the ancient Vinger Royal Road, which connected Norway and Värmland, Sweden as well as on the north-south Norwegian route along the Glomma. As Kongsvinger formed a key junction point for these routes, fortifications were constructed there to protect against invasion from the east.
