One day we were walking down the street, and my brilliant hubby who can now read most of Czech signs noticed a poster talking about the tour of a newly renovated underground passage around Old Town Hall and Zelny Trh. It seems that they spent more than EUR 3M to make it happen. It was finally opened for public. Being curious ourselves, we went to Old Town Hall and made a reservation for a tour on Oct 10th.
The tour started by going down the spiral staircase at the eastern edge of Zelny Trh. Unfortunately we couldn't understand most of what the guide was saying (I wish they prepared a brochure or something for non-Czech speakers), but it seems that some of the rooms will have some kind of exhibitions in the future. At the time we went, it was basically empty.
The tour took about an hour and we all came out from the other edge of Zelny Trh. Sorry not too much information about this somewhat interesting pathway, but I will try finding more information about it. In the meantime, I wanted to share the pictures with you :)
