The buildning was designed by architect Ragnar Östberg, and built between 1911 and 1923. Consisting of eight million red bricks the building is centered around two large squares, an outer yard and and and indoor hall. The indoor hall was originally intended to be in blue, and is also called the "Blue Hall", or Blå hallen, despite the fact that Östberg changed his mind and decided to keep the red bricks, because he found color more beautiful. The Blue Hall is perhaps most well known for as the dining hall used for the banquette held after the awarding ceremony of the Nobel Prizes each year. At the top of the 106 meter tower the Three Crowns are visible, which is an old national symbol for Sweden.
