The Ringstrasse is a road, slightly more than 5 km (3 miles) long, that circles Vienna’s inner city. Ordered built by Emperor Franz Joseph in the mid-19th century, many of the most important buildings in Vienna line both sides of the street: palaces, museums and stately homes. 

Buildings along the road include the State Opera, the Natural History Museum, City Hall and the Vienna Stock Exchange. The buildings represent various architectural styles, and are all considered architectural masterpieces. Construction of the Ringstrasse started in 1857, with the street opening in 1865.
