All of the Polish coastline was under German control from the 18th century through the end of World War I in 1918. Poland became independent of Germany and Russia as a result of World War I, but between the two world wars its coastline was only a narrow "corridor" at Gdynia. As a result, all of the pre-1945 lighthouses except the three Gdynia lights are of German construction. The historical German names for these lighthouses are shown in curly braces {}. At least four lighthouses were destroyed during World War II, and many of the others suffered severe damage.
