The organ with thirty-four voices

The south tower of Fredrikskyrkan houses a carillon of 35 bells. Installed in 1967 by the Bergholtz Bellfoundry, the bells are part of a clock that chimes three times every day.

Construction began in 1720 to replace a temporary wooden structure. Governor Salomon von Otter laid the first stone, and the building was eventually consecrated in 1744. Although Crown Prince Adolf Frederick attended the ceremony, the church was named to honor Frederick I. Nicodemus Tessin the Younger designed the building in the Baroque style, with the characteristic spires reaching completion in 1758.

The pulpit dates back to 1854, designed by Johan Adolf Hawerman, and was installed before the altar. A baptismal font features carvings from a gift by the ship builder Gilbert Sheldon. The church silver is kept in a massive safe to ensure its preservation.

The first organ was moved from the previous wooden church, but in 1764, Lars Wahlberg built a much larger instrument with 34 voices driven by six large bellows. That organ served the parish until 1905, when it was replaced by a Stockholm-built instrument which remains in use today after a reconstruction in 1982-87.
