Old Town, Oslo
Around 1290 the Franciscans established its monastery in the south-eastern outskirts of town during the north-facing slope of Ekeberg (current Ekeberg slope). In 1299 King Eirik II Magnusson died. As he had no sons, his brother took over the throne as Haakon V Magnusson. King Haakon had Oslo as his ducal seat while his brother was king, and he made Oslo to his permanent royal residence. At the same time he started construction of the Akershus Fortress, as weapons development made the palace an easy target for artillery from Ekeberg Hill. In the early 1300s, St. Mary's Church was converted into a large brick cathedral with two strong west towers - a landmark for the entrance to the city.
