This is the building which houses the stock market of Belgium. Situated in the heart of the city, it is one of the most regular hangout destinations for the locales. Just sit on the staircase in front of the buildings and watch the world go by. The architecture of the building too needs mention for its intricate detailing and exquisiteness. The best time of the day to visit the Bourse is during dusk when the stock market is already closed.
