Spring (April-May) and Fall (September-October) offer pleasant weather for climbing the tower and smaller crowds. Summer (June-August) provides the best chance for bright, clear days, ideal for panoramic photos, but is the busiest period. Winter offers a unique, often snowy, perspective of the city's rooftops.
Comfortable, sturdy walking shoes are absolutely essential for the 172-step climb|Wear layers of clothing, as it can be cool inside the historic halls but windy and exposed at the top of the tower|There is no formal dress code, but respectful attire is appreciated for a visit to a historic and cultural monument.
Originally a Dominican monastery in the 11th century, the Klementinum was transformed into a major Jesuit college in the 16th century, becoming a powerhouse of the Counter-Reformation. It housed a university, a printing press, a pharmacy, and a library that was one of the most important in the Jesuit world. After the suppression of the Jesuits, it became part of Charles University and now houses the National Library of the Czech Republic.
Cancellation policies vary depending on the specific tour operator and ticket option you choose. Many of our partners offer free cancellation up to 24 hours before the tour start time. Please check the specific conditions of the ticket you select during the booking process.

Real experiences from real travelers
Honestly, this was the highlight of our trip. The Astronomical Clock is famous, but the Klementinum is the real deal. You can't walk inside the library, but seeing it from the entrance is enough to take your breath away. The view from the tower is 100% worth the climb. Our guide was funny and full of interesting facts. Booking online was easy and saved us from queuing.
The library is as beautiful as everyone says, a true work of art. The climb to the tower is not for the faint of heart, but the panoramic view of Prague is your reward. It was spectacular! I'm giving 4 stars only because I wish we could have spent more time just looking at the library. The tour feels a bit rushed, but it's well-organized.
I was looking for something less crowded than the main square and this was perfect. The entire complex is beautiful and serene. The guide's explanation of the Meridian Hall was fascinating - true science history! The view from the top is much better than Petrin Tower in my opinion. Highly recommend booking the first tour of the morning.
It's a beautiful place with a lot of history. However, be very aware that you only see the library from behind a rope at the door. You cannot go in. Also, the stairs are very narrow and steep. If you have any mobility issues, this is not for you. The view is nice, but the main draw (the library) feels a bit like a tease.
Wow. Just wow. The Baroque Library looks like something out of a Harry Potter film, but real. It's utterly magnificent. The climb up the tower was a good workout, and the 360-degree view of the city is unparalleled. I got some of my best photos of Prague from up there. A must-do experience.
We visited in February and the view of a snow-dusted Prague from the tower was pure magic. The tour was informative and the guide was excellent. It's a short tour, about 50 minutes, which was perfect for a cold day. Seeing the old astronomical tools was very cool. Easy to book, no issues at all.
A very interesting tour that shows a different side of Prague's history, focusing on science and education. The Mirror Chapel was a surprise, so beautiful. The library is the star, of course. I just wish the group was a little smaller to hear the guide better in the stairwells. But overall, a great value and a fantastic experience.
Don't let the 172 steps deter you! The view from the Astronomical Tower is absolutely phenomenal and gives you a true sense of the city's layout. The library itself is a work of art that has to be seen to be believed. Our guide was passionate and knowledgeable. We booked our tickets through this site's partner, GetYourGuide, and it was a seamless process with mobile tickets.
Everything you need to know for your journey
No, visitors cannot enter and walk among the books in the Baroque Library. This is to preserve the fragile, historical books and frescoes. You will be able to view and photograph the magnificent hall from the doorway, which provides an excellent perspective.
Yes, photography is allowed, but strictly without the use of flash to protect the delicate artifacts and artwork. Tripods and selfie sticks are also generally not permitted due to the narrow spaces.
There are 172 steps to the top of the Astronomical Tower. They are part of a historic, narrow spiral staircase. There is no elevator, so a moderate level of fitness is required.
The tour can be interesting for older children with an interest in history or science. However, the long climb and the fact that it's a guided tour with a lot of historical information might not be engaging for very young children. Parents should use their discretion.
It is highly recommended to book your tickets online in advance, especially during the peak tourist season (spring, summer, and holidays). Tours have limited capacity and can sell out quickly. Booking ahead guarantees your spot and preferred time.
For the best photography lighting and potentially fewer crowds, consider booking the first tour of the morning or a late afternoon tour during the 'golden hour' just before sunset. On a clear day, the views are spectacular at any time.
Unfortunately, due to the historic nature of the building, there are no elevators. The tour is not wheelchair accessible and is not recommended for visitors with mobility challenges due to the numerous steep stairs.
Tours are offered in multiple languages, with English being the most frequent. When booking your ticket through our platform, you can typically select a tour in your preferred language, such as German, French, Spanish, or Italian, depending on the operator's schedule.
It is crucial to arrive at least 10 minutes before your scheduled tour time. Due to the strict schedule and limited group sizes, latecomers may not be able to join their tour and may be required to purchase a new ticket for a later time slot, subject to availability. Refunds are typically not provided for missed tours.
