The Place du General de Gaulle ( also known as the Grand ' Place ) is in the heart of Vieux Lille , a district of cobbled streets , shops , restaurants , cafe , and an assortment of architecture ranging from the beautiful 17th-century Vieille Bourse ( Old Exchange ) to the 20th-century Nouvelle Bourse and Opera .
The cobbling on the streets of Vieux Lille is replaced every year .
