You need to be selective in Charleroi itself for parts of the city are dirty and less salubrious. Charleroi’s Museum of Photography shouldn’t be missed though as it holds a comprehensive collection of camera equipment and the art produced with it that has few equals.
From Charleroi, the E19 west goes to Mons which holds some unique attractions for tourists. The main square has the city hall which dates from the 15th century and which comes complete with a lucky monkey outside said to bring good luck to all who pat its head. The square is also the scene of the annual mock medieval battle called the Lumecon. It’s quite a spectacle! Finally, the artist Van Gogh lived in Mons for a brief period and you can visit the house in the Rue de Pavilion.
Go east on the E42 to Namur, a city with a very French feel. It’s best known for the imposing citadel on the top of the hill which presides over the city. In the Convent of the Sisters of the Sacred Heart there are fabulous examples of Mosan Art by the acknowledged grand master, Hugo d’Oignies.
