Castle Hill, Newfoundland and Labrador
|Location||Placentia, Newfoundland and Labrador, Canada.|
|Official name: Castle Hill National Historic Site of Canada|
Castle Hill is an area containing the remains of both French and British fortifications, overlooking the town of Placentia (formerly known as Plaisance) in Newfoundland and Labrador, Canada. The site was originally established in order to protect the French fishing interests in Newfoundland and the approaches to the French colony of Canada.
French forces successfully raided British settlements during times of war while Fort Royal, atop Castle Hill, protected the colony from attack by British warships. In 1713, the French gave up their right to settlement in Newfoundland and established a new stronghold at Louisbourg on Cape Breton Island. British settlers replaced the French and their soldiers garrisoned the fortifications until 1811.
