Hosted by Arts Gowanus the weekend of Oct. 16-17, Gowanus Open Studios is Brooklyn’s biggest celebration of local art and artists. More than 400 artists and venues in the greater Gowanus neighborhood will open their doors, giving the public a rare glimpse inside the former factories, warehouses, and studio buildings of this vibrant neighborhood. Artists will be on hand to discuss their work, share their processes, and showcase their latest projects. Partner businesses in the neighborhood will be offering discounts. (noon to 6 p.m.; FREE)
