St. Stephen’s Basilica is one of the most popular tourist attractions in Budapest because of its architectural beauty. Another reason is the observation deck. You can climb 364 steps or take an elevator to the top in order to enjoy a 360° view of the city. Szent István Bazilika is 315 feet tall, the same height as the Hungarian Parliament dome. This equality symbolizes the balance between church and state. No building in Budapest can be taller than these two landmarks.
