Very interesting! - This was a great tour that gave us all the information needed about the clock. The guide was very knowledgeable and explained everything well. The weather wasn’t great that day so we spent most of the time inside the building. The views were amazing from top of the tower! Overall it was a nice tour and I’d recommend it.

Must do while in Prague! Fantastic - Beautiful tour with informative narration of the city. Our guide was fantastic and spoke perfect easy to understand English. Great description of the clock and the walk to the top is worth it. Definitely recommend while in Prague.

Icing on the cake - Absolutely the most characteristic square in Prague! Full of people, it is beautiful to admire. The watch is the icing on the cake. Beautiful both day and night

Astronomical clock - Medieval astronomical clock - 1410, located on the wall of the city hall of Prague. It is interesting for its history, uniqueness and characteristics.

Most visited attractions in Prague - To get a good look at the clock it is better to go early in the morning when there are few people because every hour it fills with crowds.

...more than 600 years thus making it the oldest astronomical clock in the world which is still operational.... - One of the most famous tourist sites in Prague is its Prague Astronomical Clock. It is attached to the Old Town Hall in Prague’s Old Town Square. I understand that it was first mounted in 1410, making it the third oldest astronomical clock in the world. It has been in continuous operation for more than 600 years thus making it the oldest astronomical clock in the world which is still operational. On the hour large crowds of tourist assemble in front of this celebrated clock to hear its chimes and movements and the parade of the Apostles. But I found it was more interesting to read about the two main parts. The upper colorful circle is the astrolabe, and the lower circle is the Calendar Board. Just as an example of this extra knowledge there are three sets of numbers on the main dial: Roman numerals; Gothic numerals and Arabic numerals, many tourists never notice this major item. Finally, I found the best time to view this famous astronomical clock is in the early morning around eight am, long before the crowd’s line up in front of this famous clock.

Rough start, but something not to miss - I wish I realized that we had selected our tour time before we arrived, and had the option to add the the additional town hall and under ground tour, with our original ticket to plan better for the time needed for this tour. The guide was very knowledgeable, but we did not realize that we needed our phones for the audio guild, and felt a little uncomfortable having to sign in to my email on the streets of Prague. It was truly a nice experience, once on our way, and I would recommend adding the town hall and underground tour , to the time spent here

Disappointing watch - The visit to the town hall and the climb to the tower are really worth it, the clock with its famous mechanism is quite disappointing compared to expectations.

Something disappointing - On the site it is suggested through photos that you can see several things, but that is not the case. You can't see the halls of the town hall, except for a small room behind a rope. If you want to see the cellars, you will have to pay extra for a tour. You will get an explanation of the various parts of the town square and their history and explanation of the clock. Then you can climb the tower. Oh, that's it. Then I think this is pretty expensive.

Not much of a tour - This was not much of a tour. We met our guide and he walked us a few blocks to the clock tower. He stopped several times along the way to talk about historical events. The problem was the streets were very crowded and the tour guide spoke very softly. You could not hear a word he was saying. You would be better off purchasing tickets at the clock tower and doing a self guided tour.
