The St. Gallen Monastery Library is the most treasured of St. Gallen. It is located in the center of the German-speaking city of St. Gallen in northern Switzerland. The monastery library has a history of more than 800 years and has a collection of over 100,000 books. Because it contains hundreds of priceless parchment manuscripts from the 9th to 13th centuries A.D., it is one of the oldest libraries in Europe and has been awarded World Cultural Heritage by UNESCO. The library is small, divided into two open floors, the whole building and St. Gallen Monastery, holy and solemn. The bookshelf is equipped with cages. Books displayed behind the cage are a national treasure. St. Gallen is not very big. Although there is public transport, it is better to walk to the monastery library.
