The very cool retro-futuristic SNP Bridge (now known officially as the "New Bridge") was built in the late 1960s and early '70s at the height of Communist excess. It was inspired by the optimistic futurism of the 1960s and looks like it sprang right out of an episode of Star Trek or The Jetsons. The circular observation deck atop the supporting tower rises some 90m (295 ft.) above the river below. The view from the top is great, but the shape of the deck, the winds buffeting the bridge, and the flowing river below all combine to cause a slight feeling of vertigo. The restaurant serves good, if expensive, food -- and if you're eating at the restaurant, you can visit the observation deck for free.
