At the foot of the Prime Tower, Ms Gerold opened her doors to the Gerold area of Zurich's Kreis 5 in summer 2012. The area behind the Freitag Tower has been transformed into a modular city garden, which is intended to create a place of encounter for the neighbourhood near Hardbrücke for a few years with its own kitchen garden, fresh cuisine, small shops, art and colourful events. Frau Gerold's garden changes depending on the season. In summer: garden restaurant, sun terrace & open-air bars. In winter: Cosy get-togethers around the campfire, in cosy parlours and with fine delicacies from 5 street food artists, a wide variety of cheese fondues and delicious raclette from Frau Gerold's kitchen.
