Maine is full of history and full of beauty. There are tons of museums and houses and other historical spots that we’ve been sending you to for years. And, of course, the hikes and nature here in Maine are unbeatable. We’ve certainly sent you to a fair few trails over the years. But this one combines both history and nature and it’s definitely worth the short ferry ride from Portland to reach it.

To find Battery Steele, head to the Casco Bay Lines Ferry in Portland for the 7-minute ride to Peaks Island. The entire island is worth exploring, but we especially love exploring Battery Steele.

Battery Steele, a military fort, was built in 1942 as part of efforts to support World War II.

It was first used by the army in the early 1900s. The first work on the area was done during World War I when the army added a searchlight shelter, a generator building and one bunker as part of the official The Portland Harbor Defenses. Later, during World War II, the Army added Battery Craven, Battery Steele, a control bunker, and five observation towers at the site.

Built to protect Portland Harbor, it was armed with two 16-inch MkIIMI guns.

It never saw any active wartime activity and in 1995, the Peaks Island Land Preserve purchased the area, preserving it as a public space. Today the land around the fort is perfect for a day outside.

When looking from the outside, the fort seems to be totally overgrown. But head inside to see the real magic. Most of the fort is underground area and features tunnels linking various parts of the structure. Today the tunnels have been used as canvases by local artists.

In fact, it has been used for the annual Peaks Island “Sacred and Profane” festival, taking place during the Harvest Moon.

We love exploring the outside, though. There are a number of small marshes and beaver dams around the fort. And if you have sure footing it’s fun to make your way through this natural area. While it’s not a hike with any real mileage, the route will take you through and around the trees, brush and water.

It’s great any time of year, but visit in the spring and summer for lots of green!

Battery Steele is always open, but be sure to watch your step as conditions can be slippery depending on the weather. The schedule for the ferry to Peaks Island varies depending on the season, so be sure to check that on the Casco Bay Lines website before heading off. You can learn more about it on the Peaks Island Land Preserve website.
