the old royal residence was transformed into a purely military fortress, the Hall was turned into a storage building. By the 18th century, its original function had been largely forgotten. However, the 19th century saw the rise of Norwegian romantic nationalism as the country gradually regained its independence. As a result, the independent medieval kingdom was used as a source of new national symbols to rally around. In 1840, it was proven that the great stone building in Bergenhus fortress was, in fact, King Håkon Håkonsson's old feast hall. For the next half century, its restoration back to its original function was debated. Henrik Ibsen wrote a poem in the hall's honor, and poet Henrik Wergeland first used the name Haakons hall in one of his poems. The hall was finally restored in the 1890s, and in the 1910s it was decorated with frescos with motives from Håkon Håkonsson's saga, and stained glass windows. The hall was severely damaged on 20 April 1944, when the wooden roof caught fire and burnt up. The fire also destroyed all the decorations from the first restoration. A second restoration took place in the 1950s, and the hall was reopened on 11 September 1961, the 700th anniversary of its first use. It is now decorated more discreetly, primarily with tapestries. Haakon's Hall is now administered by the Bergen City Museum, which also takes care of Rosenkrantz Tower and other protected buildings in the city. The hall is occasionally used for concerts, especially choir song and chamber music, and for banquets, mainly for official functions.

During his administration, the tower received its present shape and structure. The oldest part of the building is made up of a medieval tower built during the reign of King Magnus the Lawmender in the 1270s as part of the royal castle in Bergen. The keep was slightly modified ca. 1520, then extensively modified and expanded in the 1560s by Scottish stonemasons and architects in the service of Erik Rosenkrantz to attain its present form. Rosenkrantz' building contained dungeons on the ground floor, residential rooms for the governor higher up, and positions for cannons on the top floor. In the 1740s, the tower was converted to a magazine for gunpowder, a function it
