Fortification wall © David Ohmer
Guided walking tours of the three miles (5km) of city wall that surrounds the old city of Québec trace the evolution of the city's defence system across three centuries. The walls were built between 1608 and 1871 as part of the defensive system of the old city, which was the region's main colonial stronghold. The walls are set with interpretation panels and can be explored independently, but a guided tour does provide a wealth more information. Following the old walls is a wonderful way to explore the old city and visitors will pass many interesting sights in the historic centre along the way, including the Esplanade Powder Magazine. Quebec is the only surviving fortified city in North America and this fact contributed to its being named a World Heritage City.
