The Benedictine Monastery was founded 1,030 years ago on January 14, in 993 by the Bishop of Prague, St. Vojtěch, and Prince Boleslav II. Pobožný. It is still in use today.
With the founding of the monastery, the Benedictine order was given several villages in the locality, including one named Břevnová. The name was probably derived from the word břevno, a synonym for beam or log. However, since the monastery only served monks, the locals adopted the name Břevnov for the village.
