About the Area

Onset Village is often referred to as Onset the Beautiful. It is a picturesque village. Its' streets are lined with cottages of grace and elegance that overlook a sandy white beach in a tranquil bay. The essence of tranquility one gets from Onset is in touch with the spiritual aura of its' history. Onset is an Indian derived name; it "was a form of "Onkowam (for Agawam) which means "The Sandy Landing Place."

Onset is a part of the Wareham Township (est. 1739) and was originally known as Pine Point. It became known as Onset after the Onset Bay Grove Association purchased it through a "special charter . . . applied for to the Massachusetts Legislature and granted March 31, 1877. The Association was organized under that charter of April 11, 1877, at which time a code of Bylaws was adopted and officers elected. The Grove was formally dedicated to the principals of Spiritualism and the interest of human progress on Thursday, June 14, 1877." The Onset Bay Association was a group of professional businessmen who were looking for a place to establish a spiritual summer camp program.

In its' early years, Spiritualism and beauty became synonymous with Onset. It became a well-known vacation spot, an ideal place for families. It was and is still today, a village that puts a great deal of resources into maintaining its aura of spiritualism and its desirability as a vacation place. The first urban renewal effort that was undertaken in Onset was in order to revive their Spiritualism theme and image.

Onset Village as developed in a most interesting fashion. From any point on land, within minutes you can walk to the shore. Natural unobstructed beauty is everywhere. Public use of our beaches, bluffs and parks was made possible by the Onset Protective League; the Decree of 1916 has preserved them forever.

The unique manner in which roads were designed makes locating historical landmarks easy. Streets run East and West, Avenues North and South and the Boulevards circumvent the entire village. Onset's beauty is captivating. Many visitors have become residents! Please visit the Village's Web Site for more information.
