We did a tour of the cellar as well as went to the top of the tower. It was pretty cool to hear some Czech history as well as spend our time up above the tour with an amazing viewpoint of the square and city view. Highly worth the cost

This is a very old and scientifically built astronomical clock which tells an array of information which is applicable to Prague specifically. At the hour it’s quite an experience with the click coming alive . A local guide usually explains the intricate clock . Well worth many visits.Pork and sausages nearby must be tried . They are delicious. Will visit again

The clock was first installed in 1410, making it the third-oldest astronomical clock in the world and the oldest clock still in operation. The medieval tower clock is located at the southern side of the Old Town Hall Tower. When the clock strikes the hour (9am to 11pm), the procession of the 12 apostles starts and ends with the golden rooster that crows!! Fun to watch!

In today's modern world of internet, computers, 3D movies, smartphones, Instagram, and videogames, I can see why the average low attention span and uneducated American tourist will be disappointed in Prague's Astronomical Clock. And of course the hordes of tourists surrounding you while you try to video record the entire mechanical show of each hour. But give this old clock some credit! It dates all the way back to 1410...that really old! What we see now was completed in 1791, that's over 200 years old! Considering how bad most people are about math, engineering, and science in today's world...this is a really awesome old clock!

We visited for the Old Town Square for the Christmas Markets and we were not disappointed. A beautiful square with so many stunning buildings, including churches & monuments. The Christmas stalls were mainly selling delicious smelling food & drink but also lots selling Christmas gifts & novelties. The smell of cinnamon was lovely & the mulled wine. The centre piece was a huge tree decorated with baubles and lights. We visited firstly during the day and loved it but we returned the following day in the evening and it was spectacular the lights were amazing (the tree is switched on fully every evening) the whole square had a different feel to it so alive & vibrant. The food smelled even better & we succumbed to a hot dog each which was delicious plus my husband tried the old Prague ham. There was music & lights and it felt so festive it was very heartwarming to experience it. You can even go on a horse drawn carriage ride A lot busier than daytime as there were people everywhere but everyone was in good spirits. If you're there for Christmas it's a must The astrological clock area is packed when the clock is ready to chime and it's a must see but maybe a little disappointing especially for those who waited for quite a long time for a prime spot.

This is best part of Prague. It's so pretty, historical buildings, lovely restaurants/ bars around, souvenir shops, church. Such a great atmosphere. And Astronomical Clock looks so unique. I went to the top of the building, what a beautiful view of the city. Definitely one of the best city in Europe.

Absolutely brilliant, great value for money and a true insight into the history of Prague itself. Eva was an absolutely amazing tour guide who offered us a fountain of knowledge which made our trip all the better. Make sure to visit the underground areas, that was my favourite!

Great guided tour lasting just under an hour. Fascinating insight to the Old Town Hall rooms, including the cellars, and close up interior viewing point of the clock’s 12 apostles, and access to open air balcony at top of clock tower giving 360 degree views of Prague. Tour Guide, Petr, was very informative, giving concise history of the building, artefacts and city without overloading and keeping the group’s attention. Would definitely recommend this as a ‘must do’; well worth it.

Attached to the Old Town Hall in Prague, is the medieval astronomical clock. Its a very popular attraction and always attracting crowds. This clock was installed in 1410 and is the third-oldest astronomical clock and the only one still operating. We watched the hourly show depicting "The Walk of the Apostles" The figure of a skeleton during the show represents Death.

Put this on your “must see” list when you’re visiting Prague! We didn’t really know what to expect and thought it’d just be a self guided tour of an old building with a unique clock. But this was fantastic! The views from the top are spectacular and we spent a long time up there taking in Prague. The building’s history is rich and, our tour guide, Eva, really brought it to life. Walked away having had a great afternoon and feeling like we really learnt something.
