The Abbey Library of Saint Gall (German: Stiftsbibliothek) is a significant medieval monastic library located in St. Gallen, Switzerland. In 1983, the library, as well as the Abbey of St. Gall, were designated a World Heritage Site, as “an outstanding example of a large Carolingian monastery and was, since the 8th century until its secularisation in 1805, one of the most important cultural centres in Europe”.
