What place can be proud of having the widest, oldest and most precious book collection in Czechia?

The Monastery was tranformed into the Memorial of National Literature (Cz. Památník národního písemnictví) in 1953. The Strahov Library contains over 200,000 volumes, including over 3,000 manuscripts, 1,500 first prints, many incunables and "early printed books" stored in a special depository. It contains the near-whole collection of western Christianity literature, from its begginings to the end of XVIII century.
