The layout of the interior is somewhat unusual, with the choir located asymmetrically to the north and a two-aisled nave. Of the interior decoration, especially the remarkable main altar, a work by Bernt Notke, is noteworthy. It dates from 1483 and depicts, on the central panel, the descent of the Holy Ghost on the twelve apostles at Pentecost. The galleries in the church are richly decorated with scenes from the Bible, painted in the mid-17th century and probably by different artists. Of more recent origin is the organ, dating from 1929, and a commemorative plaque next to the altar, put up in memory of British sailors who lost their lives during the British campaign in the Baltic (1918–1919).
