The UFO Observation Deck sits atop one of the support pylons of the hanging New Bridge, which was constructed in the 1970s. On a clear day you’ll be treated to views in all directions, as far as Austria—and the deck is open-air, so there’s no smudged or scratched glass in the way. At 311 feet (95 meters), the observation deck isn’t exceptionally high, but Bratislava is a flat city with few tall buildings, so the views are good. Head up to the observation deck independently, or join a guided walking tour that stops by the landmark along with other attractions like Bratislava Castle.
