I always enjoy exploring medieval churches as well as abbeys. St. George's Abbey in Stein am Rhein, Switzerland, is one of my favorite places to visit.
As a former Benedict monastery founded in 970, it has a rich history to look back on. The banquet hall, containing the frescos commissioned by David von Winkelsheim (dating from around 1515) are a must-see and are considered to be the earliest proof of Renaissance influence in northern Switzerland. The cloisters are equally note-worthy. In 1525 the abbey was secularized. In 1927 the property underwent an extensive restoration and was eventually turned into a museum. St. George's abbey is a wonderful place in order to immerse yourself into the monastic life of the Late Middle Ages.
