Clay County is located in the northeastern part of the U.S. state of Florida. As of 2019, the population was 219,252. Its county seat is Green Cove Springs. It is included in the Jacksonville metropolitan statistical area.

History

Clay County was created on December 31, 1858, from a section of Duval County. Its name is in honor of Henry Clay, a famous American statesman, member of the United States Senate from Kentucky, and United States Secretary of State in the 19th century.

Clay County was once a popular destination for tourists visiting from the northern states. The therapeutic, warm springs and mild climate were major draws for visitors. Steamboats brought them to various hotels in Green Cove Springs - the St. Elmo, Clarendon and the Oakland. President Grover Cleveland was the most prominent of such tourists; he had spring water shipped to the White House. Clay County's popularity among tourists peaked during the last three decades of the 19th century. It was later eclipsed by Henry Flagler's extension of the Florida East Coast Railway to points south such as Palm Beach and Miami.

The military has also played an important role in Clay County history. In 1939, Camp Blanding opened on Kingsley Lake in southwest Clay County. The Florida National Guard developed this 28,000 acres (110 km2) complex. During World War II, it trained over 90,000 troops and became the fourth largest "city" in the state. In Green Cove Springs, Lee Field was a flight training center. After World War II, Lee Field became a base for the mothball fleet. Although Lee Field closed in the early 1960s, Camp Blanding continues to operate today as a base for military training. Clay County is also a popular choice of residence for military personnel stationed on bases in nearby Duval County (NAS Jacksonville, NS Mayport, and, before it closed, NAS Cecil Field).

Libraries

The Clay County Public Library System consists of five branches:

  • Green Cove Springs Library
  • Headquarters Library (Fleming Island)
  • Keystone Heights Library
  • Middleburg-Clay Hill Library
  • Orange Park Library

The first public library in Clay County was made up of a small collection established by the Village Improvement Association within the county. Other small libraries were established by other organizations within Clay County. In 1961, representatives from different women's organizations in the county started a movement to establish a library system within the county, and resulted in the Clay County Board of County Commissioners beginning to set aside funds to create the county library system. Due to their efforts, the first public library in Clay County was opened in 1961 in Green Cove Springs. The Green Cove Springs Library purchased a bookmobile in 1962 and began to provide outreach services to different areas within Clay County that same year. In 1962 two more public libraries opened in Clay County, the Keystone Heights Library and the Orange Park Library. A fire destroyed the Keystone Heights Library in February 1962. The Keystone Heights Library was relocated to a new building in Theme Park in 1964. The Headquarters Library in Green Cove Springs became open to the public in 1970 after a population boom caused the need for a new library. In 1976, the Orange Park Library moved to a larger location within the town of Orange Park. The population growth experienced in the county during the late 1970s necessitated the development of the Middleburg-Clay Hill Library, which first opened in a storefront in the late 1970s. The permanent facility for this library was completed and opened to the public in 1986.
