Edward and Frans Van Raemdonck were siblings who were killed while serving in the Belgian Army in World War I. Born in Temse in East Flanders, both brothers had volunteered for the Belgian Army in 1914. They were serving together in the 6th Company of the 24th Line Regiment when both were killed in an attack on the hamlet of Stampkot, near Steenstrate, on the night of 25–26 March 1917, aged 18 and 17 respectively. In the aftermath of the conflict, the deaths of the "Van Raemdonck brothers" became part of Flemish popular mythology as a result of its symbolism of brotherly love and self-sacrifice. Their flamingant views and the supposed indifference to their fate among their French-speaking officers meant that it became increasingly associated with the Flemish Movement in post-war Belgium. Their fate was widely commemorated in monuments over following years and the brothers were symbolically reburied at the Yser Towers (IJzertoren) monument in 1932 and was an important part of the annual Yser Pilgrimage (IJzerbedevaart).

The Yser Towers are a monument near the Yser river at Diksmuide in Belgium. It was built to commemorate the soldiers killed on the Yser Front in World War I and pacifism but subsequently became an important political symbol for the Flemish Movement.

The current tower was rebuilt alongside the remains of the original and was finished in 1965. It remains a site of political significance to Flemish nationalists and is the center for their annual Yser Pilgrimage (IJzerbedevaart).
