Nelson-Mandela-Platz: climate-resilient hub in the northeast of Vienna

From the very beginning, it was clear: this was not to be just a series of stops. Wide paths, high-quality natural stone paving, plenty of greenery, and numerous seating areas make the square a place where you can arrive briefly and also meet up.
The bus and tram stops are particularly striking: not only do they provide shelter from wind and weather, but their green roofs also create a strong visual statement for public space. For this design, the station roofs were awarded an architecture prize by the City of Vienna / MA 19.

Hot summers make it clear how important climate-resilient squares are. At Nelson-Mandela-Platz, many elements work together: large-canopy trees, shaded areas, and smart rainwater management based on the sponge city principle.
Instead of simply channeling rainwater into the sewer, it is stored beneath the square and made available to the trees when they need it. This provides cooling, improves the microclimate, and gives the roots enough space to develop well. In winter, the system is adjusted so that salt-laden water does not seep into the ground.

What you don't see at first glance: the square is also part of a research project. In the “Internet of Trees”, selected trees were equipped with sensors in the ground. Among other things, they measure moisture at different depths. This makes it possible to determine where water is needed – and where it is not.
An additionally funded “main tree” with an extended sensor set provides particularly extensive data, making the square an open-air laboratory for climate-resilient urban development.

In addition to its role in the neighborhood, the square has regional significance. With the U2, Aspern Nord can be reached from Praterstern in around 17 minutes. From here, there are direct connections to Vienna’s city center and Vienna Central Station in the west, as well as to Bratislava in the east.
Nelson-Mandela-Platz thus helps position Seestadt as a regional center in the northeast of Vienna – as a well-connected, climate-resilient location for living, working, and arriving.
