The Ringstrasse or Ringstraße (pronounced [ʁɪŋˌʃtʁaːsə] ⓘ, lit. ring road) is a 5.3 km (3.3 mi)[1] circular grand boulevard that serves as a ring road around the historic city centre, the Innere Stadt, of Vienna, Austria. The road is built where the city walls once stood. The Ring, as it is colloquially known, was built, along with grand buildings on either side of the road, in the second half of the 19th century. The road runs clockwise, from the Urania to the Schottenring, and is divided into nine parts.
Because of its architectural beauty and history, the Ringstrasse is designated by UNESCO as part of the Historic Centre of Vienna World Heritage Site.[2]
