Galeries Royales Saint-Hubert

You're standing in a street with a roof on it. The Galeries Royales Saint-Hubert opened in 1847, designed by Jean-Pierre Cluysenaar, and the idea was simple: take lanes too narrow for carriages, cover them in iron and glass, and let the shops trade in daylight whatever the weather. The glass overhead runs about 18 meters up. The Galerie du Roi and the Galerie de la Reine are each more than a hundred meters long, and the Galerie du Roi measures 213 meters end to end, a bit over eight meters wide, two city blocks under one roof.
Walk on and look to your right at number 23 in the Galerie de la Reine: Neuhaus has sold chocolate there since 1857, and it was in that shop, in 1912, that the praline was invented. You'll come out by the Grand-Place. Before you leave, look up at the central peristyle: it lost its glass in the last century and got it back in 2016, following the original drawings.
