Citadel Church

The Citadel Church is a Baroque chapel within the pentagon-shaped Kastellet fortress in Copenhagen, designed with white and pearl grey interior walls, gilded accents, and three large oil paintings set in carved wooden frames. The interior creates a bright, orderly appearance with classical ornamental details that enhance the elegant atmosphere of the space.

Built between 1703 and 1704 under King Frederik IV by architect Georg Philip Müller, the church served as a garrison chapel within the military fortress. Its construction occurred during a period when Copenhagen's defensive structures were being reinforced as part of the city's strategic development.

The church hosts services for both military personnel and civilian parish members of the Copenhagen Diocese, creating a shared spiritual space that brings together different communities. This dual role reflects how the fortress itself served both defensive and civilian purposes over time.

The church is located at Kastellet 50 in Copenhagen and welcomes visitors during weekday hours, with regular services held throughout the week. Keep in mind that access may occasionally be limited since the site is an active military fortress with ongoing operations.

The building features special sound holes in its structure that allowed prisoners in an adjacent prison complex built around 1725 to hear religious services. These architectural details show how the fortress was designed to serve multiple purposes, including providing spiritual care to those held in custody.
