Tongeren is the oldest city of Belgium and mostly known for Ambiorix. Antwerp artist Joachim introduced street art with a giant wall on the outside of primary school 't Atheneeke'. 

The students were allowed to brainstorm for the artwork: "The students have been asked what school reminds them of," says principal Chris Vandormael. "The answers were very varied: studying, for some, school means getting up early, but also great friendships and feeling good in class."

The young street art artist Joachim put the ideas of the students in a sketch. "Pictured, you see a figure that literally absorbs knowledge," says Joachim. “The liquid in the cup from which he drinks represents that knowledge. In his open brain pan, the brain has given way to light bulbs that symbolize ideas. ”
