Prince Carl Philip's crown, Prince Karl XIII's crown, lay on a cushion to the right of the altar.
Princess Sofia Albertina's crown lay on a cushion to the left of the altar.
The crowns were made by Johan Adam Marcklin for Gustav III's coronation in 1772.
At the coronation of Gustav III there were no crowns for his brothers Prince Karl and Prince Fredrik Adolf. His sister Sofia Albertina was also without a crown. So jeweller to the King, Johan Adam Marcklin, was tasked with fashioning three new princely crowns. The three crowns were made of gold, which came from melting down a toilette service that had been kept in a closet since 1743 and once belonged to Ulrika Eleonora the Elder.
The Seraphim standard from 1810 stands to the right of the altar.
The standard is on display as Prince Carl Philip is a Knight of the Order of the Seraphim. The standard is displayed at the christenings, weddings and funerals of the royal personages who are members of the Order of the Seraphim.
