What is "norrbro"

Norrbro ( Swedish: "North Bridge") is an arch bridge over Norrström in central Stockholm. It extends north from the northern front of the Royal Palace passing over Helgeandsholmen in front of the Riksdag building, and from there over to Gustav Adolfs torg. Norrbro was designed by the city architect Erik Palmstedt (1741–1803) in a neoclassical style.
