1. Old Quebec, also known as Vieux-Québec, is the historic heart of Quebec City and is a designated UNESCO World Heritage site. It is one of the oldest settlements in North America and a prime example of a fortified colonial city.

The city is divided into two main areas: the Upper Town (Haute-Ville) and the Lower Town (Basse-Ville). The Upper Town sits atop Cap Diamant, offering panoramic views of the St. Lawrence River. It is characterized by its charming cobblestone streets, historic buildings, and iconic landmarks such as the Château Frontenac, the Notre-Dame de Québec Basilica-Cathedral, and the City Hall.

The Lower Town is located at the base of Cap Diamant and can be accessed by the funicular or through a series of stairs. It is home to Petit-Champlain, one of the oldest commercial streets in North America, lined with boutique shops, art galleries, and restaurants. The area also features the historic Place Royale, which was the site of the first permanent French settlement in North America.
