The B/ON-1146 Commando Bunker is a preserved German World War I military structure located in De Panne, West Flanders, Belgium. It is part of the extensive network of fortifications built by German forces along the Belgian coast during their occupation. The bunker has been maintained as a historical site and is open to the public, offering insight into early 20th-century coastal defense engineering.
The surrounding region of the Westhoek was heavily fortified during both world wars, with De Panne being a significant location in the Atlantic Wall during World War II, though this specific bunker dates to the earlier conflict.
