Years: 1290 - 1290
The first construction on the Akershus Fortress, built to protect Christanstad, started around the late 1290s, by King Haakon V, replacing Tønsberg as one of the two most important Norwegian castles of the period (the other being Båhus).
It is constructed in response to an earlier attack on the city by the Norwegian nobleman, Earl Alv Erlingsson of Sarpsborg.
