From the 1920s through the 1940s, William Lyon Mackenzie King (the 12th Prime Minister of Canada) had these walls (now in disrepair) built at his Gatineau Hills estate 'Kingsmere' near Ottawa. Dry stone walls were used to create beautiful boundaries at both Moorside and Kingswood residences. King said of the walls that, "...the improvement they made to the property was even more than one would have imagined..." Over the years significant sections of these walls have gradually deteriorated; now they are in need of careful and loving restoration.
