One of most historic landmarks in Prague, the library is old and has many old books one of them from the third century!! You cannot go further inside one two meters and take pictures without flash because they have to maintain certain temperature and humidity!
Another cool thing, you can go up to the tower and enjoy the view of the old town from above!
Must Visit :)

Interesting to visit because of its uniqueness. Mind the fact visitors cannot, in fact, enter the library. Rather, they are allowed to take pictures from the door.

Fun experience visiting this absolutely gorgeous and breathtaking library & astronomical tower. We weren't able to go inside the library room itself, as to preserve it. I wasn't aware of that fact prior to purchasing the guided tour, so I was a bit disappointed , but understand why that rule is in place. Still a great experience!

had an excellent christmas concert at the mirror chapel. sound was very good with organ, violin, cello and soprano. should book your seat in advance and head there at least 15min b4 time to get a decent seat as it is free seating.

Die Bibliothek selber ist nicht zugänglich. Im Rahmen einer Führung für 12 Euro kann man jedoch über einen kleinen Balkon einen Blick reinwerfen. Schon beeindruckend! Zur Führung gehört der Aufstieg auf den Turm (172 Stufen), kein Aufzug! Inkl. Observatorium und Wetterstation!
Dauer insg. ca. 50 Minuten, die absolut lohnen!

Great place! Full of history. Organized tours with stories about the library. Unfortunately the library cam only be seen from the entrance door in order to preserve books. Great view of Prague from the tower!

Great historical place to see. The library itself can only briefly be seen from the outside, but to prevent any damage to this legendary library, this is the right thing to do. The rest of the tour with the astronomy tower, including the view over Prague from the top was breathtaking. Two thumbs up as well to our guide Miro!

The most beautiful library of the world , very very ornated which holds soooo many books and tge view from the tower was great.
Only bad thing is I booked the time slot that was narrated by a Czech speaker but on the website it didn't specify which language will be spoken. Also the time is very limited to be there.

We were so glad we visited! The views were amazing and the library was beautiful. Book ahead or stop by in the morning to reserve tickets. We went to grab tickets one afternoon and the remaining timeslots were somewhat limited. The steps at the top are super steep, I have a hard time with heights and coming down was a little slow-going for me.

Be aware of the “first hour 50% off discount” because they only do it if there are sufficient people in the first hour!!!!! Kinda of a scam but okay.
Regarding the price it’s okay, not super cheap but at least a nice view and explanation of the library and astronomical tower

An in-depth guided tour gave us the history of the library and the building. Climbing a steep staircase, on each floor we stopped and our guide would talk if through the purpose of that floor through history. The main library room is heavily restricted as it is extremely well preserved which means it can only be viewed from a small area inside the doorway and the lights are dimmed to help with the presentation. It is no less beautiful though. The view from the top of the tower is one of the best.

Tickets sold out very quickly so make sure you book in advance.

I found it overrated. The sightseeing tour lasts only 50 minutes. The tourists are not allowed to enter the library and have only a few minutes to take a look inside. And it is rather dark inside, so you won't see a lot. The overlook terrace is nice, but very narrow, and you have only 10 minutes to take pictures.

The library and view are wonderful. I could stay in the library for hours and hours, it’s a shame you can only look in and can’t really enter into it.

Our tour guide was mediocre at best, he didn’t really know anything and suggested if we had any questions to google them or go to the National Library next door.

The library as genuinely one of the most beautiful places I have ever seen, so it’s definitely worth seeing, just don’t expect much from the tour.
