In 1910, the current iron lighthouse was built according to the standard design of the Swedish lighthouse engineer Nils Gustav von Heidenstam (* 1822; † 1887), who specialized in this field. The main static feature of the structure is its adaptability to sandy soil. It is a tube with a diameter of 1.9 meters, reinforced on the outside with profile structures, with a gallery and a lantern at the top. The total height of the lighthouse was 19.2 meters. The new lighthouse received a rotating kerosene lantern controlled by a clockwork mechanism. Despite the adapted design of the lighthouse, bank erosion remained a problem that had to be addressed. In 1938, a protective wall was built using tree trunks. The Pape lighthouse survived both world wars without damage. During World War I, when the front approached the lighthouse, the lighting equipment was dismantled and taken to Russia. When the Germans took over the area, they installed a new acetylene lamp. This lantern worked until the 1940s and was then replaced by an electric one. In 1971, the lighthouse was restored and its total height was brought to 22.3 meters. Currently, an electric light bulb in a stationary concentric band lens is in operation. In 1993, the range of the light was increased and the shore fortification was reinforced with concrete blocks. In 2003–2004, the lighthouse underwent a long overhaul.
