Plan of Saint Gall
The Plan of Saint Gall is a medieval architectural drawing of a monastic compound dating from 820–830 AD. It depicts an entire Benedictine monastic compound, including church, houses, stables, kitchens, workshops, brewery, infirmary, and a special building for bloodletting. According to calculations based on the manuscript's tituli the complex was meant to house about 110 monks, 115 lay visitors, and 150 craftmen and agricultural workers.
