The Doon Pioneer Tower is a National Historic Site, administered by Parks Canada. The Tower was erected on one acre of land located on the old Betzner homestead, chosen in part because of the existence of the old pioneer graveyard. It was built by the Waterloo County Pioneers' Association, formed in 1923, as a memorial to the early Mennonite-German pioneers, who migrated to the area in 1800. The monument is constructed of field stones in a Swiss style. Constructed in 1925-26, the Tower was designed by Toronto based architect William Langton.
