• Two ways up the tower, by lift or a 365-step staircase, to the Three Crowns at 106 meters
• The Nobel banquet hall is the Blue Hall, which has no blue on its walls, something kids can check for themselves
• 18 million mosaic tiles cover the Golden Hall upstairs, with scenes from Swedish history to pick out

Stadshuset, the seat of Stockholm's city government, stands at the water's edge facing Riddarholmen and Södermalm, built from nearly eight million dark red bricks.

Inside, the Blue Hall hosts the Nobel Prize banquet and holds Scandinavia's largest organ, with 10,270 pipes. Upstairs, the Golden Hall is covered in more than 18 million mosaic tiles showing scenes from Swedish history. The 106-meter tower is topped by the Three Crowns.
