Fort Saint Louis (Newfoundland)

In 1662, the French had established a strategic trading post in a well protected cove overlooking Placentia Bay that separates Avalon to the rest of Newfoundland and near the Grand Banks.

Fort Saint Louis was built inside the harbor in order to protect the small port city of Plaisance from an enemy attack.

Its enclosure was nearly 250 meters long, encircling two bastions, the headquarters of the governor and the buildings of the garrison.

The fort was attacked during King William's War in the Battle of Placentia (1692).

In 1713, the Treaty of Utrecht forced the French to abandon their settlements in Newfoundland.
