This church houses the bodies of the Swedish monarchs. It is on the island of Riddarholmen, near the Royal Palace in Stockholm. Today the church is only used for burials and commemorative purposes. Many Swedish monarchs are buried here; it is one of the oldest churches in Stockholm, with parts dating back to the thirteenth century, when it was first founded as a monastery. After the Reformation, the monastery was closed and the building was transformed into a Protestant church. On the walls of the church are the coats of arms of the Royal Order of Seraphim (the Swedish royal order of chivalry).
