  • Sunnyside Estate on the eastern bank of the Speed River. At front entrance on circular driveway
  • On the Sunnyside Estate front entrance is a small horizontal dial on a white pedestal surrounded by a flower garden. The original of this sundial is reputed to be the one that was mounted on the stump of the tree felled by John Galt in his ceremonial founding of Guelph on April 23rd, 1827. The original dial and pedestal were carved from Guelph limestone, and are in very poor condition. They were moved indoors during renovations in 1979. A replica now stands in the original position. See NASS Compendium Vol. 6 No. 3, Sept. 1999.
