St. Gallen Abbey

The Abbey Library of Saint Gall is one of the oldest and most significant monastic libraries in the world, housing approximately 170,000 volumes including over 2,000 medieval manuscripts. In 1983, the library and the surrounding abbey district were designated a UNESCO World Heritage Site in recognition of their exceptional cultural and historical importance.

The abbey originated from a 7th-century hermitage established by the Irish monk Saint Gall (Gallus), who traveled from Ireland as a companion of Saint Columbanus. The site evolved into a major Carolingian center of learning by the 8th and 9th centuries, becoming one of the most important monastic and intellectual hubs in medieval Europe.

No, the Abbey of Saint Gall was dissolved in 1805 during the secularization reforms of the Napoleonic era, and it is no longer an active religious house. The former abbey buildings now serve civic and religious functions, including housing the cathedral of the Diocese of Saint Gallen.

The Plan of Saint Gall is a famous 9th-century architectural drawing of an idealized Benedictine monastery complex, created around 820 CE and preserved in the abbey's library. It is the earliest surviving large-scale medieval architectural drawing and provides invaluable insight into Carolingian monastic design and daily life.
