Fearless reporter Tintin and the Smurfs are Belgium’s most iconic comic heroes, but that’s just the tip of the iceberg in this land obsessed with the so-called “ninth art”. You’ll want to make a pitstop at the Belgian Comic Strip Center (housed in another Horta masterpiece), but more fun still is to do a self-guided tour along the comic strip trail. This journey through endless eye-popping murals is a brilliant way to explore the city’s lesser-known corners.
