Monastery of St. Gallen

The Benedictine Abbey of St. Gall, or the Monastery St. Gallen, was founded in AD 613, and is an independent principality (state) in Switzerland. The library is thought to be the richest Medieval literature library in the world.
An original architectural drawing, known as the Plan of St. Gall, was found of the backside of a work called The Life of St. Martin, created from five pieces of parchment sewn together. The architect who made the plan may or may not have designed it in its current state, but it is known that he dedicated it to Abbot Gozbert, who lived in the early 800s.
