The reconstructed Fort William Henry at Pemaquid includes many of the 17th century fort's original stones. It is part of the Colonial Pemaquid State Historic Site in New Harbor.

The original Fort William Henry was built on the site of two previous forts in 1692 after the English army regained control of the area. When the fort was destroyed in 1696, the English again abandoned Pemaquid. After Father Rale's War, Colonel David Dunbar, Surveyor-General of the King's Woods, rebuilt the fort in 1729–1730, renaming it Fort Frederick. After acquiring the site of the fort, the State of Maine began reconstruction of the tower and wall bases in 1908, an effort led by historian John Crawford.

The caption reads, "Fort William at Pemaquid, Maine."

The Tichnor Brothers printing company published this type of postcard circa 1938.
