Fort Popham is a Civil War-era coastal defense fortification at the mouth of the Kennebec River in Phippsburg, Maine. It is located in sight of the short-lived Popham Colony and, like the colony, named for George Popham, the colony's leader. The site is preserved as Fort Popham State Historic Site.^[2]
