On 3 November 2021, the artwork "NEBULA" was inaugurated at a vernissage on the Limmathof terrace. NEBULA" is the extraordinary work by artist Antonina Businger, with which she gives the Mercier footbridge in the "Bäderquartier" an unusual and dreamlike look through a light installation. "Nebula" by Businger is an early kick-off for the 2022 "Bäderfest" which has been postponed for a year due to Corona. The work can be admired until January 2022.
