The Battlefields Park

The Battlefields Park includes the Plains of Abraham with Des Braves Park, both within Quebec City, and forms one of the few Canadian national urban parks. Its significance lies in the Battle of the Plains of Abraham, the British victory over France, which decided the development of Canada. Established as a park by law on March 17, 1908, it features an interpretive centre and walking trails, and is sometimes used for outdoor concerts, especially during the national festival events . The park contains a collection of about 50 historical artillery pieces scattered about its grounds. It is managed by the National Battlefields Commission, a federal government agency under the Minister of Canadian Heritage with members appointed by the Queen in her Canadian, Ontarian, and Québécois Councils. The commission also oversees its own police service since 1948.
Built by the British to prevent the Americans from drawing close enough to lay siege to the walls of Quebec, the four Martello towers were begun by James Craig in 1808 and completed in 1812. The towers were arranged to provide for each other's defence, being situated along an axis that bisects the Plains of Abraham from the northwest to the southeast in order to screen the western approach to Quebec City, and were numbered rather than named. Tower No. 3 was demolished in the 1900s but the other three remain. The limited openings on the tower were designed to prevent the enemy from taking it by storm, while the tower's rounded shape and thick masonry walls made it nearly impervious to artillery fire.
