The Strahov monastery was founded in 1143. In the 17th century it was rebuild into its today’s baroque form. There's a very beautiful library inside (Theological and Philosophical hall). They're a must see. The Basilica of the Assumption is also a real beauty. The monastery was forcibly dissolved by the communists in the 1950s and all the monks were sent to the labor camps. It's working again today. The monastery has it's own brewery (founded around 1400) and an adjunct restaurant that comes highly recommended. The breweries beer is called Saint Norbert. The whole place is one of the most important monastic complexes in the Czech republic.
