Argentia is a former unincorporated community and current commercial seaport and industrial park in the Town of Placentia, Newfoundland and Labrador, Canada. Originally a fishing settlement known as Little Placentia, it became a major U.S. military base during the Second World War. Today, the site is used for port operations, ferry service, and industrial development.

History

Argentia began as a fishing community and was renamed from Little Placentia after silver was discovered nearby. Its history changed dramatically in 1941 when it became the site of a major U.S. military base, leading to the relocation of many residents.

Second World War significance

Argentia hosted a major Allied military installation during the war and afterward. The Atlantic Charter was agreed to offshore in 1941, giving the site lasting historical importance.

Current use

After the military base was abandoned, the site was developed into a commercial port and industrial park. It also serves as the terminal for a seasonal ferry service between Newfoundland and Nova Scotia.
