Step into a world of baroque splendor at the Klementinum, a vast historic complex right in the heart of the Old Town. Your guided tour will grant you a peek into the breathtaking Baroque Library Hall, a truly magical space you can admire from the doorway. Afterwards, prepare for a climb up 172 narrow steps inside the Astronomical Tower; the effort is well worth it for the stunning panoramic views over Prague's fairytale rooftops.
