Western Poland is a museum of old transmission towers which were built before 1945 when this area was part of Germany. This disused pole in Lesna/Marklissa already existed in 1907 and served the voltages of 40kV/10kV, but the upgrade to 40kV happened later, before 1925. Today around Lubomierz some of these poles still exist, but as part of the 15 kV distribution grid.
