From towering cathedrals and grandiose chapels to simple wooden churches nestled in the picturesque countryside, religious architecture in Switzerland serves as a profound testament to the country's rich cultural and spiritual heritage. Over the centuries, these sacred structures have evolved, reflecting the religious, social, and artistic currents of their time. In the 16th century, the Reformation, particularly under the influence of John Calvin, dramatically reshaped the religious landscape of Switzerland. As Protestantism took hold, many existing Catholic churches were repurposed for Protestant use. This transformation led to the removal of ornate decorations, statues, and altars, replacing them with a focus on simplicity and functionality. The pulpit was moved to a central position, emphasizing the importance of preaching and the Word of God. The 20th century brought another wave of transformation to Swiss religious architecture, marked by the embrace of modernist principles and bold experimentation with new materials and forms. Architects like Walter Maria Förderer pioneered the use of raw concrete and sculptural spaces, reflecting a desire to express spirituality in new, contemporary ways.
