About this source
What it is
St. Pierre Cathedral is a historic church in Geneva, Switzerland, begun around the 12th century in Gothic style. Since 1535 it has served as the principal church of the Protestant Church of Geneva, closely associated with John Calvin's preaching.
Why it matters
During the Reformation, the cathedral's interior was stripped of its rood screen, side chapels, and decorative artworks, leaving the plain, bare space that Calvin and his fellow reformers believed suited true worship, free from what they saw as distracting ornament. The building stands as physical evidence of how the Reformation changed not just belief but the appearance of churches themselves. Calvin's successor Théodore de Bèze was later buried there, linking the site to the generation that carried Calvin's work forward.
Look closer
- What changes to the cathedral's interior tell us about Reformed beliefs about worship and images?
- Why might reformers have seen stripping away decoration as a positive, religious act rather than destruction?
- How does a building like this preserve history differently than a letter or book does?
