Lyon is the third largest city in France and the capital of the Auvergne-Rhône-Alpes region, located at the confluence of the Rhône and Saône rivers. It was designated a UNESCO World Heritage City in 1998. The landmark Basilica of Notre-Dame de Fourvière sits atop the hill, blending Byzantine and medieval styles, offering a 360° panoramic view of the city's red-tiled rooftops. Vieux Lyon (Old Lyon) is the largest Renaissance district in Europe, with cobblestone streets, colourful buildings and 'traboules' (hidden passageways) full of ancient charm. The 15th-century astronomical clock in Saint-Jean Cathedral, the Bartholdi Fountain on Place des Terreaux, and the ruins of the Gallo-Roman theatre are all historical treasures. As a world capital of gastronomy, must-try dishes include quenelles de brochet with sauce Nantua, Cervelle de Canut, Lyonnaise salad, and rosette de Lyon; for dessert, the tarte aux pralines (pink praline tart) is recommended. Traditional bouchons offer an authentic taste of local cuisine.
