Parish church St. Nikolai, Parish church in Forst, Germany

St. Nikolai church in Forst is a parish building with a square west tower that rises above the rest of the structure. The interior contains vaulted spaces and several chapels, with the tower completed in 1570 and later fitted with three cast iron bells.

The church began construction around 1400 as a gothic building, with the vaulted interior finished by 1516. Later changes added a chapel and transformed parts of the building through baroque alterations.

The church shows in its buildings how different architectural styles were layered over time, with both gothic and baroque elements visible to visitors today. The space continues to serve as a gathering place for the local community and those who come to see its structure.

The church stands in the town centre of Forst, its square west tower visible from afar. The interior was restored from 1992, and the tower was rededicated on the First Sunday of Advent 1992. The Bonhoeffer Chapel, formerly the Jacob Chapel of 1508, and the crypt with Heinrich von Brühl's coffin can be visited.

Heinrich von Brühl, the Saxon-Polish prime minister, lies in the crypt beneath the baptismal chapel, now the Bonhoeffer-Kapelle. His wooden coffin was replaced by a zinc one in 1905, and an urn holding his intestines stands before it. He bought the Forst estate in 1740–1746 and helped rebuild the town and church after the 1748 fire.
