You can't miss this place! Its probably one of the only few modern architecture building in Prague, its now a hotel, but you can go inside and up to the viewpoint for free. The only catch is that you have to buy a drink, but the are reasonably priced, considering what they could be charging.
Once you go up you are spoilt with a beautiful panoramic view of Prague and its wonderful bridges and buildings.
Prague's most outstanding modern architecture stands out in the historic background. At an intersection of busy road, we did not go inside but took a walk across the bridge and enjoyed the beautiful view of the Vltava river.
