By the 19th century, its original function had been completely forgotten, and it was sometimes referred to as "the old church". However, the 19th century saw the rise of national romanticism in Norway 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.[5]
