Quebec City resonates with history, and nowhere is it most evident than in the beautifully-preserved Fortifications of Quebec. These restored 17th-century walls, built atop of plunging cliff, tower over the St. Lawrence River. As the only remaining walled city in North America, Quebec City is now recognized as an UNESCO World Heritage Site, and a must-see on a visit to the city.
The Fortifications of Quebec encircle Upper Town, from the Citadel of Quebec through Parc L’Esplanade and Artillery Park National Historic Site, then down toward Quebec City Old Port (Vieux-Port). You can walk the 2.9-mi/4.6-km circuit on top of them, where you can take in sweeping view of the city and St. Lawrence River. The fortifications' Interpretive Centre has a small but interesting exhibit on the history of the walls as well as an old gunpowder building from 1815.
