The Budapest Exchange Palace is one of the most iconic buildings constructed at the turn of the 20th century in the Hungarian capital, a primary example of the monumental public architecture typical of the Austro-Hungarian Empire. Prominently located on Szabadság Square, in the heart of the city centre, Exchange Palace, designed by Hungarian architect Ignác Alpár and completed in 1907 was the largest Stock Exchange building in Europe when it was erected. The building has an area of roughly 50,000 sq m gross and is 141 meters long, spanning across an entire block.
