About this source

What it is

The Plan of Saint Gall is a medieval architectural drawing from around 820-830, dedicated to Gozbert, abbot of the Abbey of Saint Gall. It depicts an entire Benedictine monastic compound — church, houses, kitchens, workshops, infirmary and more — and is kept at the Abbey library of Saint Gall in Switzerland.

Why it matters

Though never built, the Plan shows how the ideals in Benedict of Nursia's Rule — prayer, work, hospitality and enclosure — were imagined in physical form by monks of the Carolingian period, centuries after Benedict's death. It is the only surviving major architectural drawing from the long period between the fall of Rome and the 13th century, making it a rare window into how medieval people planned monastic life.

Look closer

  • Why might monks have wanted to draw an 'ideal' monastery that was never actually built?
  • What does the plan's inclusion of workshops, an infirmary and guest housing tell you about what the Rule expected of a monastery?
  • What might be missing from a plan like this that we would need other sources to learn?
