The Canton Marketplace is the first building which begins the Trade Days market area on Highway 19. It is a climate controlled indoor pavilion with over 300 vendors who are mostly year round regulars. This pavilion has slightly more upscale items than the rest of the grounds and a food court. Despite the upscale feel, you can still find excellent bargains on unique items. Sometimes you can catch concerts or other free venues during trade days weekend here. Their restrooms are the best found anywhere on the grounds and there is a winery which offers taste testing. They have convenient onsite parking, an RV Park, and offer a free trolley transportation to the other First Monday areas.
