Storkyrkan (Swedish: [ˈstûːrˌɕʏrkan], lit. 'The Great Church'), also called Stockholms domkyrka (Stockholm Cathedral) and Sankt Nikolai kyrka (Church of Saint Nicholas), is the oldest church in Stockholm. Storkyrkan lies in the centre of Stockholm in Gamla stan, between Stockholm Palace and Stortorget, the old main square of Stockholm. It was consecrated to Saint Nicholas in 1306 but construction of the church probably started in the 13th century.
