Butchart Gardens, Victoria, BC, Canada

Robert Pim Butchart began manufacturing Portland cement from 1888 to 1909 near his birthplace of Owen Sound, Ontario, Canada from the area’s rich limestone deposits. In 1909, when the limestone quarry was exhausted, Robert’s wife Jennie set about turning the former quarry into the Sunken Garden, which was completed in 1921 and is on the Canadian Register of Historic Places.
