Runnymede was the name given to the house that John Scarlett built near the intersection of Dundas and Keele in 1810 or so.
By the late 1940’s the house had been converted to a garage and used car dealership.
You can still make out the decorative brick details on the corners.
The name Runnymede may be derived from the Anglo-Saxon runieg (regular meeting) and mede (mead or meadow), describing a place in the meadows used to hold regular meetings. The Witan, Witenagemot or Council of the Anglo-Saxon Kings of the 7th to 11th centuries was held from time to time at Runnymede during the reign of Alfred the Great. The Council met usually in the open air. This political organ was transformed in succeeding years, influencing the creation of England’s 13th century parliament.
