Nikolaikirche

Nikolaikirche is a church building in Siegen that combines a hexagonal central structure with a three-nave layout. The structure features a baroque tower dome and large windows that fill the interior with natural light.

The building was constructed before 1250 as a late Romanesque hall church and served as a market church surrounded by merchant shops during the Middle Ages. Later modifications transformed it, with the baroque tower dome reflecting renewal during the early modern period.

The church houses a golden baptismal bowl made of Peruvian silver from the 16th century, a gift from Prince Johann Moritz of Nassau-Siegen. This donation reflects the connection between the city and wealthy rulers who had traveled to distant lands.

The church tower contains four large bells, three of which have rung over the city for more than 500 years. These bells shape the soundscape of Siegen and can be heard from many parts of the city.

A large golden crown has topped the church spire since 1658, placed there by Prince Johann Moritz, while the original crown hangs in the tower hall. These two versions tell the story of centuries of decoration and preservation of the building's crowning element.
