The large stainless steel towers are ventilation shafts. They provide fresh air and exhaust for the underground parking garage beneath the square. They were transformed in autumn 2018 into a vibrant, colorful artwork by the internationally renowned Argentine-Spanish street artist Felipe Pantone.
In 2013 I started with a new hobby. In the beginning it was difficult to get reliable information how to find streetart in public space. In 2016, I had the idea of sharing my information with other street art enthusiasts and started my blog “Streetartwalks”. When I found out about this new street art community at the beginning of 2018, I was immediately on board.
