St. Johns County is a county located in the northeastern part of Florida, a state in the United States. In 2020, about 273,425 people lived here. The main city and county seat is St. Augustine. However, the nearby community of St. Johns actually has more people living in it. St. Johns County is also part of the larger Jacksonville, Florida region.

The county was officially created in 1821. It was one of the very first two counties formed after Florida became part of the United States. This happened at the start of the Florida Territorial period. The county was named after the St. Johns River, which flows along its western side.

Many people who live in St. Johns County travel to Jacksonville for work. These areas are often called "bedroom communities" because people mostly live there and commute elsewhere for their jobs. Tourism is also a very important part of the county's economy. This is mainly because of the historic city of St. Augustine and the many golf courses in the area.

A Look Back: History of St. Johns County

The story of St. Johns County began in 1821. That's when Colonel Robert Butler officially received East Florida from Spain. He was representing Major General Andrew Jackson, who was in charge of Florida for the U.S. government. Jackson decided that all the land east of the Suwannee River would be named St. Johns County.

St. Johns County was created on July 21, 1821. This was just 11 days after Florida was given to the United States. It was also five days after the city of St. Augustine became an official city. At the same time, Escambia County was also created in the former West Florida area.

The name "Saint John's" came from an old Spanish mission built around 1580. It was called San Juan del Puerto, which means "Saint John of the Harbor." In 1932, the U.S. government removed the apostrophe from the name. This was because an apostrophe usually shows ownership, and they wanted the name to be simpler.

In the beginning, St. Johns County was huge! It covered most of peninsular Florida, more than 39,000 square miles. It was about 475 miles long and 165 miles wide. Much of this land was not inhabited. St. Augustine (founded in 1565) was the oldest permanent European settlement in the area. There were also many Native American communities living in the county.

County Symbols: Coat of Arms

St. Johns County has a special symbol called a Coat of Arms. It tells a story about the county's past.

  • The main part of the design has a silver lamb (called an Agnus Dei) on a green background.
  • The lamb holds a silver flag with a red cross. This is a direct symbol of the county's name, "Saint John."
  • At the top, there's a red section with a gold castle. This castle has black lines for its stones and red windows and doors. It represents the strong fort built in St. Augustine, which is part of the county.
  • Around the edge, there's a border made of eight parts. These parts switch between a red square with a gold castle and a silver square with a purple lion standing on its hind legs. These symbols come from the old coats of arms of Castille and Leon in Spain.
  • At the very top, there's a special crown called a mural crown. It looks like a gold wall with twelve gold towers, though only seven are usually seen in drawings. This crown represents a province or region.
