Climb up to St. István’s tower (300+ steps), and you’ll be rewarded with a fantastic view out over the city — and a welcome breeze during Budapest’s hot summer. According to city law, no structure can be built higher than the towers of St. István and the dome of Parliament. They both measure 96 meters (315 ft) tall and count as two of the three largest buildings in Hungary. And as you’ll discover, 96 is the magic number all over Budapest, due to the 1896 millennial celebration.
