St. Maria Neudorf, Catholic church in eastern St. Gallen, Switzerland

St. Maria Neudorf is a Catholic church in St. Gallen featuring a symmetrical design with two round windows and a central dome with small openings. The structure combines Art Nouveau elements with modern religious architecture and is complemented by a parish center and house connected via covered galleries.

St. Maria Neudorf was built in 1914–17 to designs by Adolf Gaudy, regarded as his most important church. The large rose window over the west entrance was taken from the Dörflikirche of the 1914 national exhibition. The parish centre and rectory were later attached to the east side, linked to the church by a covered gallery. The building is listed as cultural property no. 10145 in St. Gallen.

The large rose window above the west entrance was made for the Dörflikirche at the 1914 national exhibition and later moved here. Inside, Fritz Kunz painted the murals and Richard A. Nüscheler of Zurich made the stained glass. The covered gallery links the church, parish centre and rectory and frames the church square on two sides.

The building is linked to community spaces and a parish house, making it a hub for religious gatherings and community events. The covered connections allow easy movement between different areas regardless of weather conditions.

The organ installed in 1927 features 87 registers with about 4000 pipes, including a special distant work placed beneath the dome. This setup allows sound to project downward from above, creating an uncommon acoustic experience.
