Bunker 1-86 is a military fortification located near Gdynia, Poland. Built in 1936, it is part of Poland's interwar defensive preparations along the Baltic coast. The structure represents the strategic military architecture of the Second Polish Republic during a period of rising tensions in Europe.
The bunker's location near the Baltic Sea made it part of Poland's coastal defense network. Its construction predates World War II by several years, reflecting the Polish military's efforts to strengthen national defenses in the 1930s. The numerical designation '1-86' suggests it was part of a larger system of fortifications.
Today, the bunker stands as a historical monument to Poland's military heritage from the interwar period. Like many similar structures from this era, it provides insight into the defensive strategies employed by smaller European nations in the years leading up to World War II.
