Medieval Riddarholmskaya church is the main burial place of Swedish monarchs. It is located on the same island Riddarholmen (translated as "Island Knights"), near the Royal Palace in Stockholm. The congregation was dissolved in 1807 and today the church is used only for burial and memorial services, as well as a museum, a monument of history and a place for exhibitions and other events. Swedish monarchs found their last resting place here, since Gustavus Adolphus (d. 1632) and ending with Gustav V (d. 1950), the only exception being the Queen Christina, who rests in St. Peter's Basilica in Rome. The earliest burial belong to Magnus III (d. 1290), and Charles VIII (d. 1470).

The church is one of the oldest in Stockholm, still preserved some parts of which date back to the late 13th century, when the Franciscan monastery was located Greyfriars. After the Reformation, the monastery was closed and converted into a Protestant church.

The church has three naves, built in the Gothic style, but the brick building at once acquired a modern look. The initial draft of the spire of the building was designed by Willem Boy and hoisted to its rightful place in the reign of Johan III (1537 - 1592 years), however, already in 1835 it was destroyed by lightning and was replaced by cast-iron spire, which survived until our days. It was under Johan III Riddarholmskaya church has experienced the highest dawn and found its finery.

The walls of the church you can see the coats of arms of the Knights of St. Seraphim. If one of the knights of the Order dies, his coat hanging in the church, and in the day of the funeral for an hour sounds chimes.
