The monument is located next to the supermarket where eight people were killed in the last and most terrible terroristic assault of a series in Belgium between 1982 and 1985.

A gradient of polished stones turns from dark red to bright yellow, matching the autumn colour of the eight ginkgo trees planted above. Together, they create a ‘sunrise of hope’, 38 years after the tragic event.
