Riddarholmen, literally The Knights Islet, is an small island in the center of Stockholm, Sweden. The island forms part of Gamla Stan, the old town, and houses a number of private palaces from the 17th century. The main attraction of Riddarholmen is the church, Riddarholmskyrkan, which served as the royal burial church since the 16th century and where a number of Swedish monarchs lie consecrated.
The palaces of Wrangel, Hessenstein, and Schering Rosenhane are today used by Svea hovrätt, the appelate court for Svealand, while the Swedish Government Court resides in the Stenbock Palace. Some of the older Swedish Government Agencies, like the Chamber College of Sweden and the Chancellor of Justice, are also located on the island.
