The St. Gall Plan is a medieval blueprint for a monastic community, created around the year 820 by an unknown monk at the St. Gall Abbey in present-day Switzerland. This plan outlines the layout and organization of a monastery, including essential buildings such as the church, cloister, and living quarters, emphasizing the importance of order and functionality in monastic life. The plan serves as a significant historical document, reflecting the architectural and social ideals of the Benedictine monastic tradition. It illustrates how monasteries were designed to support religious practices, education, and agriculture, contributing to the cultural and economic life of the region during the Middle Ages.
