Regelbau 514 is a standardized German military bunker design from World War II, part of the extensive Regelbau series of fortifications. These bunkers were mass-produced according to standardized plans to meet the Wehrmacht's defensive needs across occupied territories. The Regelbau system included hundreds of different types, numbered from 1 to 704, each designed for specific military functions such as troop shelters, ammunition storage, or command posts.
The Regelbau 514 type was specifically developed as part of Germany's defensive infrastructure during the war, with publications and modifications to the designs continuing from 1938 onward. These standardized bunkers represent a significant aspect of military engineering from the era, showcasing the systematic approach to fortification construction that characterized German military planning during World War II.
