St. Mary's catholic church

St. Mary's is a Catholic parish church in Olten featuring a three-nave basilica design with supporting columns and without a transept. The Neoromanesque style shapes the overall appearance of the building throughout.

Hermann Baur designed this church in the early 1900s when Olten's Catholic population was growing rapidly. The building arose to meet the increased needs of the expanding community.

The church serves as a spiritual center for Olten's Catholic community and reflects the religious needs that emerged during the early 1900s. You can see how the building remains a gathering place for locals throughout the week.

The church is located at Frohburgstrasse 1 in Olten and welcomes visitors interested in exploring its interior. Regular services take place during the week, so checking opening times beforehand is helpful.

The interior holds religious artworks depicting biblical narratives that give the space spiritual depth. This artwork collection shows how faith messages were expressed visually during that period.
