A World War I-era Belgian military bunker located near Visé in the province of Liège. The designation 'B/ON-2260' follows Belgian military nomenclature for fortified positions, and 'Wz 22' likely refers to a specific model or construction plan from the period. This region was part of the fortified position of Liège, a key defensive line during the 1914 German invasion. The bunker represents the smaller, dispersed concrete pillboxes and infantry shelters built to support the larger forts and delay enemy advances.
The structure is situated in a rural area close to the Dutch border, a sector that saw significant fighting in August 1914. While the main forts of Liège have been extensively documented, many of the smaller accompanying bunkers and trench systems like this one remain less studied. Its concrete construction reflects the transition in fortification techniques from the late 19th to early 20th century.
No specific details on armament, crew, or exact construction date are provided in the available information. The bunker is a relic of the static warfare that characterized the early phase of World War I on the Western Front before the conflict devolved into prolonged trench warfare further north.
