Abby of St. Gall
The Abby of St. Gall is located in the northeastern part of Switzerland. A small town (St. Gall) is home to the Abby since the 8th Century and the Abby Library is one of the oldest in the world. There you can find some of the oldest manuscripts existing on parchment. Not only can you "not touch" but you must remove your shoes and put on felt shoes that will not damage the floor.
