This lake was originally the fish pond where the nuns of the Benedictine convent of St. Marien went out to get some fresh air from their long and tedious times of reclusion and where they looked for the answers to their prayers, either by fishing or taking a walk in this haven of peace.
Unfortunately no fish survived, but you can see some ducks, rabbits, squirrels and of course, the crows.
There are 4 playgrounds for kids, with a sandbox and different themes, a lot of place for picnics, for walking the pets and for summer games (and some winter ones if the weather allows it), feeding the ducks and sunbathing (… if it gets sunny), far away from the maddening crowd. But unfortunately you can’t swim in the lake.
The park is split in two by the Kantstraße, but there’s a pedestrian tunnel to cross from one side to the other under the bridge.
In the southwest half there’s a boat house that is a café and beer garden, the Bootshaus Stella am Lietzentsee.
My biggest kid prefers the playground that is in the south-west close to the Herbartstraße and Dernburgstraße corner, because is less crowded and there’s a toboggan shaped like a plane, complete with a pilot’s cabin.
I personally prefer to sit on the bench by the cascade-like fountain, facing the lake, either for a picnic or just to feed the ducks.
