In 1998, Abby Mandel returned from the sustainable farmers' markets in Europe and was inspired to start the Green City Market in Chicago. Abby began with a list of nine local farmers, but the amount of vendors has rapidly grown through the years. Today, you'll find the market at Lincoln Park between May and October, consistently happening on both Wednesday and Saturday. In August, September, and October, you'll also find a second location in Fulton Market District. If you have the urge to visit during a colder month, stop by the Peggy Notebaert Nature Museum, where the market continues, albeit in smaller form, two Saturdays out of the month.
