Louisbourg - the scene of two major military sieges in the Anglo-French wars for supremacy in North America. The fall of Louisbourg to the British in 1758 paved the way for the capture of Québec and the end of French rule in North America.
The fortifications at Louisbourg were systematically destroyed by British engineers in 1760 to prevent the town and port from being used in the future by the French, should the peace process return Cape Breton island to France. The British kept a garrison at Louisbourg until 1768.
