This Italian Neo-Renaissance arcade is considered one of Europe’s oldest “malls.” Charged by King Leopold I with its construction in 1837, young architect Jean-Pierre Cluysenaars converted the entire Rue Saint-Hubert into the airy arcade that visitors see today. Three levels – the King’s gallery, the Queen’s gallery, and the Prince’s gallery – are home to boutiques, cafes, newsstands, and even a cinema. Musicians stroll the arcade, hoping for an appreciative Euro or two. Shop and restaurant hours vary, as do accepted credit cards, but the gallery itself is open daily around the clock, so you can appreciate the architecture any time of day or night.
