Company PGE Polska Grupa Energetyczna has commissioned a professional team to constitute one of the biggest eco murals of the world. Located in the mountains of Bieszczady, on the barrage by Lake Solińskie in Poland, this “painting” wall of 91 meters wide and 54 meters high representing Bieszczady’s wildlife and plantlife was created with water under high pressure to clean the sediment that was formed during many years.
