In 2018 the CENTRALA reconstructed a ‘water bowl’ in front of the Zachęta building — a basin with water plants. The concrete planters that once appeared in the Warsaw space were used for water holes — they created a network of ponds to irrigate and aerate the city. This flower bed concept was designed together with staff from the University of Warsaw Botanic Gardens, and then replicated elsewhere in Warsaw and in Gdańsk and Kielce, making a large-scale comeback for urban water gardening.
