The Strahov Monastery (Strahovsky klaster) was founded in 1140 by Vladislav and completed in the 17th and 18th centuries. It functioned until the Communist Government closed it. Now it is a working monastery and a museum. Inside is the Church of St. Roch, the Church of the Assumption of Our Lady and the Strahov Picture Gallery. The biggest attraction is the Strahov Library, which is the largest (and more than 800 years old) monastic library in the whole country – this is the main reason for visiting. Once you are there, you will also appreciate the best city views from the foot of the Strahov Monastery.
