Beneath the triangular patch of grass encircled by traffic, a three-storey underground car park was planned. One of the car park's outer wall simultaneously constitutes a wall to the banks of the opened up ditch of the river Pleiße, the Pleissemühlengraben. The newly created green area named Mendelssohnufer brings to mind the former Gewandhaus bandmaster and founder of the first German music conservatoire with a bust depicting Mendelssohn, as well as by concrete cubes, which emulate the keys of the E minor violin concerto. The Alte Gewandhaus, destroyed during the war, was located here, as is today's still existing music college which bears his name. The integration of the underground car park and the newly configured passageways helped to appease the traffic volume in the residential district. Dedicating the roads to a green space creates a new quality of sojourn.
