Prescott, Ontario

Fort Wellington National Historic Site is a historic military fortification located on the north shore of the St. Lawrence River at Prescott, Ontario. The military fortification was used by the British Army, and the Canadian militia for most of the 19th century, and by the militia in the 20th century, until 1923, when the property was handed over to the Dominion Parks Commission, the predecessor to Parks Canada. The fort was earlier named a National Historic Site of Canada in January 1920.Built in the midst of the War of 1812, the British commissioned the construction of the fortification in 1813 to protect the head of the Gallop Rapids in the St. Lawrence. Completed in 1814, the fort was abandoned by the British shortly after the war, although it formally remained the property of the British Board of Ordnance. The British commissioned the construction of a new fort, on top of the earthwork of the first fort in 1838, during the onset of the Rebellions of 1837–1838. Completed in 1839, the fort was used by the British Army, and the Canadian Militia. The fort was used by the British until 1863, when British units left the area, making the militia the fort's sole occupant. The militia continued to use the fort until 1923, when it handed over the property to the Dominion Parks Branch, the predecessor to Parks Canada. As a National Historic Site, Fort Wellington operates as a historical open-air museum.

The Fort de La Présentation (French pronunciation: [fɔʁ də la pʁezɑ̃tasjɔ̃]; "Fort of the Presentation"), a mission fort, was built in 1749 and so named by the French Sulpician priest, Abbé Picquet. It was also sometimes known as Fort La Galette (French pronunciation: [fɔʁ la galɛt]). It was built at the confluence of the Oswegatchie River and the St Lawrence River in present-day New York. The French wanted to strengthen their alliance with the powerful Iroquois, as well as convert them to Catholicism. With increasing tensions with Great Britain, they were concerned about their thinly populated Canadian colony. By 1755 the settlement included 3,000 Iroquois residents loyal to France, in part because of the fur trade, as well as their hostility to encroachment by British colonists in their other territories. By comparison, Montréal had only 4,000 residents.In 1758, with the Seven Years' War intensifying, a French-Canadian military commander took charge of a garrison at the fort. In 1759, French military forces abandoned the fort to move to Fort Lévis. Ultimately the British besieged that fort and Montréal. After the British victories of 1760, the French ceded their Canadian territory to Great Britain. The British renamed it Fort Oswegatchie. It remained under their control until 1796, after Jay's Treaty, when redefinition of the northern boundary caused the land to be taken over by the United States. The first settlement under an American flag began that year. American residents named the town Ogdensburg after early settler Samuel Ogden.
