Massachusetts hosts the world’s largest hand‑built dam, but it remains little‑visited

The Boston Globe highlights a unique engineering landmark in Massachusetts. The structure is described as the world’s largest hand‑built dam. It was constructed without modern machinery, relying on manual labor. The dam serves as a functional water‑management facility. Despite its size, the site attracts only a small number of visitors. Local officials note the dam’s historical significance. The article suggests the lack of tourism may be due to limited publicity. Preservation groups hope increased awareness will boost visitation.
