Lexington [named for Massachusetts village where the first battle in American Revolution was fought in 1775]. The 1793 act creating Oglethorpe County named commissioners to select a site that would serve as county seat. The act further authorized the judges of the inferior court to levy a tax not exceeding 250 pounds and contract for the building of a courthouse and jail. What happened next is unclear. One source says that the settlement of Philomath [then known as Woodstock] was designated county seat, and that Oglethorpe's first courthouse was built here. However, an account of the history of Oglethorpe County states that the first courthouse was built of logs and located on the Salem Road, and that this structure was moved to Lexington in 1800. The date of Lexington's original settlement is not clear. What is known is that the General Assembly incorporated Lexington and designated it county seat in an act approved on Nov. 24, 1806.
Oglethorpe County's first courthouse is somewhat of a mystery. One source says that soon after the county's creation, the settlement of Philomath was designated county seat, and that here the first courthouse was built. Another source, however, says that the first courthouse was a log structure built on the Salem Road near present-day Lexington, and that this building was moved to Lexington in 1800. In 1806, the legislature designated Lexington as county seat. What served as courthouse from 1806 to 1887 is not known, although a volume on the history of Oglethorpe County states that the courthouse during this period was located just northwest of the present courthouse. In 1887, a new courthouse was built in Lexington of local brick, granite, and timber The most distinctive feature of courthouse is the clock tower with open areas that frames the entrance to the building. The clock in the tower reportedly weighs 1000 pounds. In preparation for the 1993 celebration of Oglethorpe County's bicentennial, the courthouse was remodeled in 1992-93.
