Cohasset is a coastal town on the South Shore, approximately 20 miles south of Boston, and its public school district serves the town's residents through Cohasset High School. The town is notably affluent, with a single-family assessed value and per capita income that rank among the higher figures in the state. Cohasset is known for its harbor, its historic village center, and its extensive conservation lands, including the Bound Brook Island and Wompatuck-adjacent trails along the water. Settled in the 1600s and incorporated in 1754, the town retains much of its colonial-era character along Border Street and the Cohasset Common.
