The Zenner is located in the middle of Treptow Park, with a view directly onto the banks of the Spree. It was built in 1821-22 as a magistrate's café in classicist style, later reconstructed in the 1950s as a restaurant with a large beer garden. In the spring of 2021, it was renovated in accordance with the preservation order and reopened as a mix of restaurant, beer garden and event location. In the future, more events such as weddings, galas and concerts are planned here.
In winter there is a winterly decorated and covered ice rink for young and old, layman or ice sports professional. Skating aids and skates are available for rent on site. On selected days, the Zenner offers curling on a total of three lanes. Also offered are specials such as ice discos and Sunday family Advent skating.
