The pilgrimage church at Birnau, completed between 1747 and 1750, stands as the most notable example of the Rococo style crafted by Austrian architect Peter Thumb. His professional life spanned the early 18th century, a period defined by significant monastic construction across Southern Germany, Alsace, and Switzerland, where he transitioned from traditional Vorarlberg building schemes toward more integrated, spatial designs.
Professional Origins
Born in Bezau in 1681, Peter Thumb was the son of the master builder Michael Thumb. He received his early technical training as a stonemason under Michael Berbig in Au before advancing his career within the Vorarlberg School. His professional network deepened through collaboration with Franz Beer, a master builder who became his father-in-law. By 1725, Thumb had secured citizenship in Constance, eventually earning a seat on the city's Grand Council in 1737.

Early in his career, Thumb utilized the standard Vorarlberg wall pier construction method for major projects, such as the St. Mauritius Abbey Church in Ebersmunster and the church at St. Peter Monastery in the Black Forest. However, he later deviated from these traditional models. During the construction of the church in Mengen between 1741 and 1744, he implemented innovative features, including a continuous gallery connected to an organ loft and arched cantilevers that provided space for side altars.
Major Works and Legacy
Thumb’s portfolio includes several significant monastic and pilgrimage sites. His work on the library at the Abbey of Saint Gall in Switzerland remains a landmark of Baroque design, contributing to the site's status as a World Cultural Heritage location. His architectural output also spanned parish churches, castles, and town residences, such as the house to the Red Dragon in Constance. He died in Constance on 4 March 1766, leaving a lasting influence on Southern German architecture.
