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.
