Storkyrkan (The Great Church), officially called Sankt Nikolai kyrka (St. Nicholas Church) and informally called Stockholms domkyrka (Stockholm Cathedral), is the oldest church in Gamla stan, the old town in central Stockholm, Sweden. Originally the principal parish church of Stockholm, it currently also serves as the seat of the Lutheran Bishop of Stockholm within the Church of Sweden since the creation of the Diocese of Stockholm in 1942. It is an important example of Swedish Brick Gothic. Located next to the Royal Palace, it forms the western end of Slottsbacken, the main approach to the Royal Palace, while Storkyrkobrinken, Högvaktsterrassen and Trångsund streets pass north and west of it respectively. South of the church is the Stockholm Stock Exchange building overlooking Stortorget and housing the Swedish Academy, the Nobel Library and the Nobel Museum.
