Lafayette County Courthouse, County courthouse in Mayo, Florida.

The Lafayette County Courthouse is a county courthouse in Mayo, Florida, constructed with Indiana limestone and Classical Revival design. The structure displays balanced proportions and traditional design elements typical of early 20th-century government buildings.

The building was constructed in 1908 using materials shipped by railroad to O'Brien in Suwannee County and then brought by wagon to Mayo. This was the county's third courthouse, following the relocation of its predecessor across the street during construction.

The courthouse remains Lafayette County's seat of government and justice in Mayo. Its name comes from the Marquis de Lafayette, and the building appears in the 1989 University of Florida Press guide to Florida's historic architecture, a listing local residents cite with pride.

The building sits in downtown Mayo and is easily accessible on foot. Visitors can explore public areas, and online resources are available for those seeking to access court records.

The building was constructed at a time when southern county courthouses were rarely built of stone. The choice of Indiana limestone was uncommon for a small courthouse in rural Florida, reflecting the county's ambition.
