Cutting-edge art is not necessarily what you'd expect to find in a stately 18th-century structure that once served as a general store, a post office, and, for 35 years, a church. Nicknamed "Old Hundred," this historic building is just part of the vast facility, which includes a 25,000-square-foot exhibition space that puts its own twist on traditional New England architecture. The white-clapboard-and-granite structure houses 12 galleries, a screening room, a sound gallery, a 22-foot-high project space for large installations, a 100-seat performance space, and an education center. Outside is a 2-acre sculpture garden. Stop by on Tuesday, when admission is free.
