Project of the Month 'April 2017'

New Appearance for Stephansplatz

Stephansplatz is one of Austria‚Äės most prominent places due to St. Stephen‚Äôs Cathedral. Therefore this important central square shall be completely refurbished and its surface redesigned. For this purpose 36,400 granite slabs and stones are laid. In addition 1,500 t of asphalt concrete and 5,500 t of drain concrete are installed. Apart from surface assembly a second drainage level for the protection of the subterranean structures (catacombs and Virgil Chapel) is established. Furthermore, essential parts of the installations are relocated or renewed.

In addition to the new surface numerous new seating-accommodations are mounted and the existing lighting is complemented. In order to guarantee barrier-free accessibility a guidance system for visually impaired persons is applied.  

On the one hand the new pavement complies with the result of the competition, which provides for some cross patterns, and on the other hand with the already changed area of Graben and Kärntner Strasse. This also creates an optical link to road spaces already renovated.

The bisection of the parking areas for horse-drawn cabs - 12 of the 24 parking areas are relocated ‚Äď brings about a significant quality improvement on Stephansplatz. This measure creates considerably more space for the pedestrians and should enable easier walking around the cathedral directly along the cathedral wall.

The construction works started in March 2017 and shall be concluded by November 2017.
