A Look at St. Marys History

The area around the St. Marys River was first explored in the mid-1500s. Spanish explorers came here as part of their efforts to settle Spanish Florida. Nearby St. Augustine was their main city. The original Spanish settlement in this area started in 1566. This makes it one of the oldest places in the United States where people have continuously lived.

After the American Revolutionary War, people in Camden County wanted to create a new town. On November 20, 1787, they signed a plan for "a town on the St. Marys." Twenty people were part of this plan. Each person received land lots in the new town. These founders are listed on a historical marker in downtown St. Marys.

The new town's first borders were near the waterfront. For a while, people called it St. Marys or St. Patrick's. Some say the name comes from the St. Marys River. Others believe it's from an old Spanish mission called Santa Maria. Georgia officially recognized St. Marys as a town in 1792. It became an incorporated city in November 1802.

Oak Grove Cemetery is part of the St. Marys Historic District. It was created outside the town's western border in 1787.

Important Treaties and Trade

On June 29, 1796, an important agreement was signed near St. Marys. This was the Treaty of Colerain. It was signed between the United States and the Creek Nation. The Creek people were the original inhabitants of this land. Langley Bryant, one of St. Marys' founders, helped as an interpreter.

St. Marys became an official port of entry for the United States in 1799. This meant ships could legally bring goods into the country here. During the early 1800s, St. Marys was a busy place for trade.

During the War of 1812, the British captured a fort near St. Marys. This was the Battle of Fort Peter. The British occupied the town for about a month. Later, during the American Civil War, the United States Navy attacked buildings along the town's shore. St. Marys was the county seat for Camden County from 1869 to 1923.
