We planned our visit to the city hall just to see the Jens Olsen's World astronomical clock. As soon as you enter you are struck by the mere size and parts of the unique clock.Even if you are no science or physics or astronomy buff, you would certainly admire the fact that the clock actually tells you the astronomical position...

While in City Hall, on the square named Radhusplandsen, sneak into the room to the right of the entrance to ogle at and be awed by the astronomical clock. It is a beautiful thing. A wondrous feat of engineering. The only thing that might top this is being aware that Archimedes created the mathematics over 2000 years ago that made... More

I don't know what to say about the Jens Olsen's World astronomical clock. It is a free exhibit located in the city hall at Rådhuspladsen (the central square) of Copenhagen. We visited because of a Trip Advisor review. It is definitely worth seeing and somewhat unbelievable that someone could have actually created the clock. It is a good-sized exhibit that... More

This is an impressive 'little' exhibition in Copenhagen's town hall. The clock is a massive (for a clock at least), shiny and intricate mechanical marvel of clockfaces, cogs and gears that Jens Olsen assembled over many years. It was finished in 1955, ten years after his death. As well as telling the current time, it calculates an array of time-related... More

The Radhaus (Copenhagen’s Town Hall) is the home of the Jens Olsen's World Clock, designed by Jens Olsen (1872–1945) and built at a cost of one million kroner. It is the most iconic part of the building. Not only does it display local time, but also solar time, sidereal time, sunrises and sunsets, firmament and celestial pole migration, planet revolutions,... More

My husband has an interest in time and space. We were thrilled to find this small and unusual ( and free!) exhibit. Quite fascinating even for the uninitiated.

I just walked into the Mayor's house in Rådhuspladsen in the heart of Copenhagen and just to the right to the little room, where Jens Olsen's World Clock is exhibited. It is expressive, thinking of the time and the patience he showed to this. Worth a visit - does not take too long. it is a small exhibition, mtne the... More

This is just a clock, BUT what a clock it is. There are so many details and interesting functionalities that it's to spend a lot of time here.

We found ourselves near City Hall on a rainy afternoon and I remembered seeing recommendations for the Clock on TA. We found that although some parts of City Hall were closed for the day, this attraction was still available to view. We spent a short while admiring the ingenuity and intricate details of this masterpiece. The room is quite small... More

I didn't know this was here, and am so glad the TA community pointed it out. It's easy to miss the entrance to the room just to the right of the main entrance to City Hall. Excellent video and prints history around the beautiful old clock in the centre of the room. Fascinating to realize the clock hasn't even done... More
