5.0Powers Gallery(1 review) - Original Fine Art Art Galleries While up to Groton, visiting my sister, we decided to go to this lovely gallery for a visit on our first venture out in a very long time. We were welcomed by their friendly, knowledgable staff and the owner, Lawrence. Their original, creative fine art is worth the trip if you are anywhere in the area of Acton. Each room, on two floors of this older house is an eye-catching display of creativity and color.Time pleasantly well spent.See more..
