Tyndall Stone was first used in the construction of Lower Fort Garry in 1832, just north of where Winnipeg now stands. Other buildings still standing as a testament to the durability of this stone are St. Andrews Anglican Church, the oldest active stone church in western Canada, built in 1845 and the Captain Kennedy House built in 1865. Gillis Quarries Limited is now the largest and longest running company to quarry and process Tyndall Stone, and is now into its fourth generation of family management.
