Fort Popham is a semicircular granite fort built in 1862 on the banks of the Kennebec River to protect Augusta from Confederate invasion. While the fort was never completed—construction ended in 1869—modifications were made and troops were stationed here for the Spanish American War and World War I.
You can visit the fort and picnic on the grounds between Memorial Day and Sept. 30. A short walk away on the Popham peninsula, you'll find Fort Baldwin, which is open year-round. If you're visiting during the warmer months, you might also want to stop at nearby Popham Beach, where you can go swimming, fishing or birdwatching—and you may even spot otters or seals.
The Fort Popham site was used for military purposes even before the current fort was built. A minor fortification was first constructed here during the American Revolution. In 1808, the federal government added a battery that became known as an “embargo fort.” The fort saw action in the War of 1812 and remained staffed until 1815.
