By the end of 2020, the marketplace in Karlsruhe will be renovated and completely redesigned. Around the city-known pyramid, bright belgrano® natural stones made of high-quality granite will be installed over the next 1 1/2 years. As a special highlight, a 180 m² fountain area will be installed in front of the pyramid and will then provide refreshment and the necessary evaporation cold in summer. The office Mettler Landschaftsarchitektur is responsible for the designs and planned the project. The new floor covering of the market square will have another special feature: the cloverleaf contours of the Concord Church will be visible as patterns in the belgrano® stones around the pyramid. During the first construction work in 2014, the remains of the old town church – in which once city founder Karl Wilhelm was buried – were found and thus symbolized.
