Here is what it looks like now after trees were removed from around it...
It's literally been hiding in plain sight for many decades under all the tree growth and vegetation...
Here is what the functioning fountain looked like way back in the day (date unknown) with kids using it...
Parks Canada tells PTBOCanada they do not know much about the fountain, other that it was a known entity.
Through the course of rehabilitating that big earth berm, it would be great to see the old fountain brought back to life. Only time will tells what happens from this Peterborough remnant of the past.
[Note that the water is not safe for drinking, as it is ground and canal water.]
