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 Manor House – one of the oldest west of Quebec – as well as a gristmill and sawmill. Johnson was responsible for settling disbanded Loyalist soldiers and their families and other refugees from the Quebec border to Prince Edward County.
