TV Tower Kamzik, Bratislava
Poking up above the hills north of Bratislava is another unique piece of Bratislavan architecture: the Kamzik TV Tower. Not quite as striking as its counterpart in Prague, it is much higher and gives much better views. The observation deck is 70 meters up, but as it sits on a 433 meter hill, that places you half a kilometer above sea level. In good weather it is possible to see the land of four countries: Austria, Hungary, Czech Republic and Slovakia.
There's a restaurant at the top to refresh you after the adventure of reaching it.
