In the 18th century, Trade was established as a trading outpost known as “The Trade Gap”. It was a trading post for Native Americans, pioneers and fur traders.  Tom Dula (made famous by the folk song “Tom Dooley”) hid out in Trade as he was on the run, suspected of murder in North Carolina. He was eventually arrested by a posse in Trade.

In 2008, the Trade Gristmill celebrated its grand opening at the Trade Community Center grounds. Most of the parts comprising the newly constructed mill date back to pre-civil war. This is a good attraction to share with family and friends.

The culture and history of Trade is celebrated at the Trade Days Festival, a long running celebration of Appalachian arts, crafts,   culture and history. It includes Appalachian music, dance and a Native American Pow-Wow.  It is held at the Trade Community Center.
