Lamont began in 1848 when a U.S. post office was established at Beasley's Store, which also served as a horse-changing station on the stagecoach line between Tallahassee and St. Augustine. After the Civil War, the small settlement that had grown up there was known locally as “Lick Skillet” and as McCane's Store. By the time its name was officially changed to Lamont in 1885, the town had grown to 180 residents, with two stores, two grist mills, and three churches. The community thrived after the Atlantic Coast Line Railroad built a line through the town in 1926, and residents worked in sawmills and turpentine stills. With the onset of the Great Depression in the 1930s, the town's industries failed, and many residents were forced to move away. Today, Lamont's past is reflected by a former post office built c. 1910 and several historic churches and houses.
