Church of Saint Boniface in Dolní Hanychov, Art Nouveau church in Dolní Hanychov, Czech Republic.

The Church of Saint Boniface is a religious building in Dolní Hanychov that blends Art Nouveau with historicist design principles. The structure displays ornamental details on both its exterior and interior, creating a cohesive architectural expression across all its spaces.

Anton Möller, an architect and builder from Varnsdorf, built the church between 1915 and 1919 for the German-speaking residents of Dolní and Horní Hanychov; World War I economic troubles prolonged the work. After the 1945 forced departure of most German speakers the building decayed and demolition was several times considered. Parishioners and displaced former residents funded urgent repairs around 2000, and it has been a cultural monument since 5 April 1994.

This serves as the spiritual center for the local Catholic community and reflects the religious traditions of the region. Visitors can see how the building remains active in village life through its ongoing use for worship and ceremonies.

The building stands on Ještědská street in the Liberec district and welcomes visitors during daytime hours. Come during religious services to see the interior in full use, or visit on weekdays for quieter exploration of the architecture.

The side tower reaches 33 metres, and the church has been a filial church of the Roman Catholic parish-deanery of Rochlice. Mass is held on Sundays at 8:00 and Tuesdays from 17:00. The pews date from the construction period of 1915–1919.
