Foto de stock - 16 April 2021, Brandenburg, Bernau: Rene Poppel, manager of the Waldfrieden outdoor pool, lays the lane boundaries of the pool. The pool, with five 50-metre lanes suitable for competition and a diving area lined with stainless steel, holds 1360 cubic metres of water and, along with a small pool, the beach volleyball facility and seating areas covered with awnings, is the heart of the outdoor pool. The pool, equipped with a solar system to heat the water, is ready to open after pre-season preparations, but that cannot yet be scheduled because of the Corona pandemic. Last summer, the hygiene concept of the facility had allowed a maximum of 200 visitors at a time. Photo: Soeren Stache/dpa-Zentralbild/dpa. - Bernau/Brandenburg/Germany
