Old Montréal is a remarkable concentration of buildings dating from the 17th, 18th, and 19th centuries. The district has the delightful feel of a Parisian-style quarter, situated as it is between the waterfront and the business hub. Its many historic sites, streets, and landmarks are best explored on foot. Those not to miss include the twin towers of Notre-Dame Basilica, the quays of the revitalized Old Port, and the open-air gathering space of Place Jacques-Cartier.
