Cape Ann Light Station Thacher Island

A National Historic Landmark

Mission Statement

In support of Rockport’s Thacher and Straitsmouth Islands Town Committee, the Thacher Island Association is a nonprofit, volunteer organization that is dedicated to the historic preservation and operation of these two unique National Historic Sites located just off Rockport’s coast. TIA raises funds and organizes special events all in an effort to preserve these exceptional sites, while facilitating visitors’ enjoyment of their scenic, natural, and cultural benefits.

We depend upon membership dues, grants, and donations to provide the funds to:

Make visits to the islands possible
Restore and maintain the historic structures, including three lighthouses, three keeper houses, a tramway and a whistle house
Improve and maintain the scenic trails, picnic and camping areas
Plant native species to encourage more birds, bees, and butterflies
Preserve the islands' unique historic and natural attributes

In addition, many TIA members provide volunteer labor to assist the Town Committee in its mission to manage and maintain the islands.
