St. Johns County is a county in the northeastern part of the U.S. state of Florida. As of the 2020 United States census, its population was 273,425. The county seat and most populous incorporated city is St. Augustine, although the nearby community, St. Johns, has a higher population. St. Johns County is part of the Jacksonville, Florida Metropolitan Statistical Area.

The county was established in 1821. It is one of the two original counties established after Florida was ceded to the United States, at the start of the Florida Territorial period, and corresponded roughly to the former colonial province of East Florida. It was named for the St. Johns River, which runs along its western border.

Today, St. Johns County primarily comprises residential bedroom communities for those who commute to Jacksonville. Tourism, primarily associated with St. Augustine and the many golf courses in the area, is the chief economic industry.

History

St. Johns County's history begins in 1821, when Colonel Robert Butler received Spanish East Florida from Captain-General Colonel José M. Coppinger. Butler represented Major General Andrew Jackson, federal military commissioner for the Florida provinces (las Floridas) with the powers of governor, exercising the powers of the Captain General and the Intendants of the Island of Cuba and the governors of the said provinces, respectively, who ordained that all the country east of the river Suwannee should be designated the County of St. Johns.

St. Johns was established, along with Escambia County (in the former West Florida province), on July 21, 1821, 11 days after Butler received Florida for the United States, and five days after the city of St. Augustine was incorporated.

The name Saint John's was derived from the Spanish mission (c. 1580) San Juan del Puerto ("Saint John of the Harbor"). The U.S. Department of the Interior dropped the apostrophe in 1932 because an apostrophe implied ownership.

It was a huge county, encompassing most of peninsular Florida, more than 39,000 square miles; it was 475 miles long by 165 miles wide. Much of the land was uninhabited. Saint Augustine (1565) was the oldest permanent European settlement, and there were Native Americans in the county as well.

Coat of arms

As described in Certification of the Coat of Arms:

In a field of green an Agnus Dei of silver, suspended on the dexter [*left side of the drawing] side of the Agnus Dei is a silver banner with red cross (as a direct allusion and symbol of the name of the County). On a heraldic chief of red is a gold castle with towers, with masonry joints in black, and with the windows and doors in red (in recognition of the fortress that was constructed in the military garrison of St. Augustine which is a part of the County).

An overall border is composed of eight parts; alternating, a red quadrilateral, with a gold castle and quadrilateral of silver with a purple lion rampant (that is to say, alternating the simplified Arms of Castille and Leon).

Given for a crest is a mural crown of a province. This is a circle of gold walls with in reality twelve gold towers with all the masonry joints in black. Only seven of the towers are visible in the drawing.

Geography

According to the U.S. Census Bureau, the county has an area of 822 square miles (2,130 km²), of which 601 square miles (1,560 km²) is land and 221 square miles (570 km²) (26.9%) is water.
