Spencer School and Silver Maple

Highlight • Historical Site

Very interesting peace of Canadian history. This one classroom school was established in 1850 and served community for over the century.
Even more interesting is the big silver maple right next to it, that was planted at the same time.
Great spot to take a lunch break in the shade of the 170 years old maple.
Enjoy and respect
