It has already become a tradition for iDSB students to enrich this very moving event at the military cemetery there with a musical or literary contribution. In addition to the Ambassador of the Federal Republic of Germany to the Kingdom of Belgium, other high-ranking officials such as the British and Dutch ambassadors are also present.
