The oldest male monastery in the Czech Republic was founded in the 10th century by Saint Adalbert, the second Bishop of Prague, with the support of Duke Boleslav II of Bohemia.
The charming Benedictine complex was rebuilt several times - due to a fire, but also because of plundering during the Hussite and the Thirty Years’ Wars. The current appearance is an example of High Baroque style and stems from eighteenth century. Most notably, Kryštof and Kilián Ignác Dientzenhofer (architects) were involved in its Baroque reconstruction.
The church of St. Margaret, the crypt and the monastery can be be visited only by a guided tour (minimum 10 people for a tour in Czech, 20 people in English or German), but the monastery garden is open to all visitors.
The monastery is also known as the oldest brewery in the Czech Republic. This tradition was renewed in 2011. You can taste the local beer in the restaurant Klášterní šenk which is located in the premises of the monastery.
The Brevnov Monastery is not far from the historical center of Prague. It's easy to get there - just a few tram stops from the Prague Castle.
