And since the 1600s there has also been a parish - the Royal Parish.
The Royal Parish's members consist of the employees of the Royal Court and their families. Every Sunday mass is held where naturally everyone is welcome.
Everyone is also welcome to the Royal Chapel's music programme featuring organ and classical music concerts.
During the summer season the chapel is open to the public twice a week, allowing a viewing of the interior, architecture and art.
Carl Hårleman completed the chapel´s interior in the middle of the 1700s, to a large part following Tessin the Younger´s drawings. Sculptures, statues and ceiling paintings have been carried out by the foremost craftsmen of the period.
