Stephansplatz - St. Steven Place

Stephansplatz - St. Steven Place

Historical landmark
1 km
The Stephansplatz is a square at the geographical centre of Vienna. It is named after its most prominent building, the Stephansdom, Vienna's cathedral and one of the tallest churches in the world. Before the 20th century, a row of houses separated Stephansplatz from Stock-im-Eisen-Platz,[1] but since their destruction, the name Stephansplatz started to be used for the wider area covering both. To the west and south, respectively, run the exclusive shopping streets Graben (literally "ditch") and Kärntner Straße ("Kärnten" is the German for Carinthia). Opposite the Stephansdom is the Haas-Haus, a piece of striking modern architecture by Hans Hollein. Although public opinion was originally skeptical about the combination of the mediaeval cathedral and the glass and steel building, it is now considered an example of how old and new architecture can mix harmoniously

Belvedere Castle

Belvedere Castle

Museum
2 kms
The Belvedere is a historic building complex in Vienna, Austria, consisting of two Baroque palaces (the Upper and Lower Belvedere), the Orangery, and the Palace Stables. The buildings are set in a Baroque park landscape in the third district of the city, on the south-eastern edge of its centre. It houses the Belvedere museum. The grounds are set on a gentle gradient and include decorative tiered fountains and cascades, Baroque sculptures, and majestic wrought iron gates. The Baroque palace complex was built as a summer residence for Prince Eugene of Savoy. The Belvedere was built during a period of extensive construction in Vienna, which at the time was both the imperial capital and home to the ruling Habsburg dynasty. This period of prosperity followed on from the commander-in-chief Prince Eugene of Savoy's successful conclusion of a series of wars against the Ottoman Empire.
