On my walking tours of scenic Charleston, visitors on vacation often ask which is the oldest building we pass, and are usually surprised that it’s made of wood – the John Lining house at 106 Broad Street. The house was built shortly after the lot was purchased in 1692, and has survived fires, earthquakes, tornadoes, and hurricanes. It has been home to a variety of people and businesses, once used as a newspaper office and for many years as a drugstore. But it is famously linked with Scottish-born physician John Lining, who was vastly head of his time in his meticulous study and understanding of fevers, electricity, climate and botany.
