Doon Pioneer Tower is a National Historic site administered by Parks Canada, reached from the Pioneer Tower Road, west from Highway 8 about one kilometre north of Highway 401.
The tower was erected on an acre of land located on the old Betzner homestead, chosen partly because of the existence there of the old graveyard. It was built by the Waterloo County Pioneers' Memorial Association formed in 1923 as a tribute to the early Mennonite settlers of the area. The monument is constructed of field stones in a Swiss style to commemorate the Switzerland heritage of many of these families.
