About Us / Grand Army Plaza Greenmarket History: Saturdays, 8AM - 4PM, year-round. The Grand Army Plaza Greenmarket was founded in 1989 as our flagship Brooklyn market, and is our second largest market behind Union Square. Located at the northwest entrance to beautiful Prospect Park — and just steps from the Brooklyn Public Library, the Brooklyn Museum, and the Brooklyn Botanic Garden — this destination market brings together a diverse mix of shoppers from the nearby neighborhoods of Park Slope, Prospect Heights, Crown Heights, and beyond. Runners, dog-walkers, families, singles and foodies all converge to buy from the huge array of farm fresh products, and to participate in the free events that take place every Saturday all year long. EBT/Food Stamps and WIC & Senior FMNP Coupons Accepted.
