The guide spoke perfect English and was very knowledgeable! It was a pleasure to participate in the tour - the library although not fully accessible, makes a lasting impression. Definitely worth it

the guide was full of really interesting information he clearly really knew his topic. he apologised for his language skills but his English was fantastic. those stairs are quite something but it was worth the climb. thanks so much.

Full description

Discover a spectacular Baroque Library and take in sweeping views of Prague on a guided tour of the Klementinum.


Meet your guide and set out to explore one of the largest building complexes in Europe. Construction of the property dates back to 1653 and today, the buildings are mostly occupied by the Czech National Library.


See the Baroque Library Hall from behind the fence. Marvel at the ornate frescoes, gilded carvings, and large globes that decorate this space. Then, follow your guide to the Astronomical Tower.


On your way there, make a stop at the Meridian Hall. View the collection of instruments housed here and learn about how this space was used to determine the exact time of noon thanks to a small beam of sunlight shining through a hole in the wall.


Finally, end your tour on a high note as you climb to the top of the Astronomical Tower. Admire sweeping views of the center of Prague and the Prague Castle from 68 meters above the ground.

This was a spur-of-the-moment tour for me, and it ended up being one of my favorite things in Prague! It was the perfect amount of time and information for what it was. The Baroque Library is gorgeous, the details of the literature and artwork, the collection of historical scientific tools — it was altogether a great presentation with the right mix to keep you interested no matter why you chose the tour or what amount of prior knowledge you brought with you. Plus, the views from the top of the Astronomical Tower are unparalleled. As a side note: I recommend doing a morning tour before it gets super warm if you’re coming on a summer day! There are some 100-200 stair steps on this tour, and not all rooms — maybe none? — are air conditioned.
