Some summer festivities include Couleur Café Festival, a festival of world and urban music, around the end of June or early July, the Brussels Summer Festival (BSF), a music festival in August, the Brussels Fair, the most important yearly fair in Brussels, lasting more than a month, in July and August, and Brussels Beach, when the banks of the canal are turned into a temporary urban beach. Other biennial events are the Zinneke Parade, a colourful, multicultural parade through the city, which has been held since 2000 in May, as well as the popular Flower Carpet at the Grand Place in August. Heritage Days are organised on the third weekend of September (sometimes coinciding with the car-free day) and are a good opportunity to discover the wealth of buildings, institutions and real estate in Brussels. The "Winter Wonders" animate the heart of Brussels in December; these winter activities were launched in Brussels in 2001.
