Mount Royal Cemetery covers 165 acres on the North slope of Mount Royal, on the site of old farms. The property extends 930 metres from east to west, and 1000 metres north to south, at an altitude of 165 to 225 metres above the city. It is one of the most beautiful garden cemeteries in North America. Laid out in a series of terraces following the topography of the mountain, the grounds are crisscrossed by footpaths and dotted with natural woodlands and flowery islets. Crab apple trees and Japanese lilacs provide rare beauty. Several species of annual and perennial flowers, including peonies and roses create an environment conducive to meditation and serenity. In winter, it is a haven for birds, drawn by the many fruit trees. Birders have counted more than 145 species. There are warblers and other migrating song birds, as well as screech owls, hawks, and nesting mocking birds.
