One of Europe's premiere old-style classical-music venues, with some of the world's best acoustics, and it is also open for tours
Cultural High Notes in a Historic Venue
Also known as the Budapest Opera, this neo-Renaissance cultural lodestar at Andrássu Út 22 in Pest was inaugurated in 1884. The Habsburg emperor of the day, Franz Josef, commissioned what was to be one of Europe's largest opera houses but stipulated that it couldn't be larger than the opera house of Vienna (co-capital of the Austro-Hungarian Empire). Even if you're not into attending one of the practically daily opera, ballet or classical-music performances, you can take the guided tour that runs several times a day. However, catching a performance here is highly recommended, especially since it's considered to have some of the best acoustics of any classical venue in the world.
