Sir John Johnson Manor House Doors Open Cornwall and SDG Counties

Sir John Johnson Manor House

Sir John Johnson (a prominent colonial military leader and administrator) founded Williamstown in 1784 after the American Revolution. He built this house – one of the oldest west of Quebec – as well as a gristmill and sawmill. Johnson helped settle disbanded Loyalist soldiers and their families. Today, it is a local museum and home to the Glengarry Archives.
