The Norstedt Building (Swedish: Norstedtshuset) is the main office of P.A. Norstedt & Söner AB on Riddarholmen in Stockholm, Sweden.
The building, designed by Magnus Isæus and built in 1882-91, features a spire-like roof, which is a well-known silhouette on the skyline of central Stockholm.
Bridge Vasabron is passing in front of the building and Gamla Riksarkivet ("Old National Archive") lies south of it.
Riddarholmen (Swedish: "The Knights' Islet") is a small islet in central Stockholm, Sweden. The island forms part of Gamla Stan, the old town, and houses a number of private palaces dating from the 17th century. The main landmark is the church Riddarholmskyrkan, the royal burial church since the 16th century and where a number of Swedish monarchs lie buried.
The western end of the island gives a magnificent panoramic and photogenic view of the bay Riddarfjärden, often used by TV journalists with Stockholm City Hall in the background. A statue of Birger Jarl, traditionally regarded to be the founder of Stockholm, is standing on a pillar in front of the Bonde Palace north of Riddarholmskyrkan.
Other notable buildings include the Old Parliament Building in the south-eastern corner, the Old National Archive on the eastern shore, and the so called Norstedt Building, the old printing house of the publisher Norstedts, the tower roof of which is a well-known silhouette on the city's skyline.
