Plan of Saint Gall

The Plan of Saint Gall is a medieval architectural drawing of a Benedictine monastic compound, dating from 820 to 830 AD and stored in the Abbey library of Saint Gall, where it remains today as Codex Sangallensis 1092. It depicts an entire monastic complex, including a church, houses, stables, kitchens, workshops, a brewery, an infirmary and a dedicated building for bloodletting, calculated from the manuscript's own labels to have been meant to house about 110 monks, 115 lay visitors and 150 craftsmen and agricultural workers. The plan was never actually built, and was so named because it is dedicated to Gozbert, abbot of the Abbey of Saint Gall; the planned church was intended to hold the relics of the monastery's founder, the hermit Saint Gall. It is the only surviving major architectural drawing from the roughly seven hundred years between the fall of the Western Roman Empire and the thirteenth century, and is considered a national treasure of Switzerland.
