OTTAWA — The United Nations Educational, Scientific and Cultural Organization has added Alberta’s Writing-on-Stone monument to its list of World Heritage Sites.

The federal government says the designation, made at UNESCO’s annual meeting in Azerbaijan on Saturday, follows more than a decade of advocacy by Indigenous groups and the provincial government.

The site, described as an “ancient and sacred cultural landscape where Indigenous peoples have created rock art for millennia,” is contained entirely within Writing-on-Stone Provincial Park.
