The Riddarholmen Church was founded in 1285 when King Magnus made a donation to the Franciscan Order to realise the construction of the Convent church at Riddarholmen.
The Riddarholmen Church of today can trace its origin back to the Convent church of the Franciscans at that time. The Franciscan friars were called Greybrothers because their clothes where grey.
The Riddarholmen Church was from 1634 until 1950 the Royal Funeral Church and many of the Swedish Kings, Queens and families are buried there. Since 1807 the church is only used only for burial and commemorative purposes and has no congregation.
