St. Gallen Cathedral (Abbey Cathedral) (St. Gallen)

St. Gallen Abbey Cathedral dominates the historic centre of St. Gallen, inviting visitors to step into a late‑Baroque masterpiece. Built between 1755 and 1770, the cathedral’s layout features twin rotundas—one to the east, one to the west—that frame a spacious nave and chancel, creating a sense of balance and light. The interior feels airy, its walls covered in delicate stucco work and vivid paintings by leading South‑German artists of the era. The design, originally drawn by Peter Thumb and refined by Johann Caspar Bagnato, showcases the elegance of 18th‑century ecclesiastical architecture.

Beyond its visual splendor, the cathedral sits at the heart of a monastic complex that began in the 7th century when Irish monk Gallus founded a Benedictine community, later formalised in 719. For more than a millennium the abbey served as a religious, economic and cultural hub, weathering the Reformation and the French Revolution before its dissolution in 1805 under Napoleon’s reforms. In 1983 UNESCO recognised the entire abbey district, including the cathedral, as a World Cultural Heritage Site.

When you enter, take time to admire the harmonious symmetry, the soft glow of the frescoed ceilings, and the quiet that still echoes the centuries of prayer and scholarship that shaped this remarkable landmark.
