Brussels is full of street art and if you have the chance, definitely go on a street art tour. Le Chat is one of the most famous cartoons in Belgium for being cynical and very on point (and for me personally perfectly embodying the Belgian way of life). Drawn and written by Philippe Geluck, a Belgian artist active since the 1970s in both Belgium and France and known for his humorous cartoons with animals. Le Chat (which is the name of the famous cat) was first designed for the francophone newspaper ‘Le Soir’ and became extremely popular rather fast.
Take a look at the multilingual street art and absorb the Belgian-nes of the jokes. They are painted on the outside wall of the police academy, if you’re lucky they do a practice patrol with their students on horses and you can see the impressive uniforms they wear. Once you’ve had enough of the plain humor you can walk around La Chasse/De Jacht for some shopping.
