The Berkshires Satellite Reef, part of the global Crochet Coral Reef, opens at the ’62 Center for Theatre and Dance at Williams College. The Crochet Coral Reef was created in 2005 by the artists and sisters Christine and Margaret Wertheim to raise awareness to the beauty and plight of coral reefs worldwide. The Berkshire iteration features hundreds of corals crocheted by community members in the Berkshires and beyond over the last year. The corals, made of a variety of colors and textures, are being assembled into a vibrant reef in the CenterStage Theatre, where lighting and sound will immerse visitors in an underseas wonderland. The opening celebration will include a dance and puppetry activation. After that, the reef will be on view through May 12 every day from 10 a.m. to 4 p.m. and Wednesday through Saturday evenings from 6 to 8 p.m. The celebration and installation are free and open to the public.
