Battery Steele, Military fortification on Peaks Island, Portland, United States.
Battery Steele spans 14 acres with concrete corridors extending 300 feet, featuring walls 18 inches thick and multiple underground chambers.
The United States Army Corps of Engineers constructed Battery Steele in 1942 with two 16-inch guns to protect Portland Harbor during World War II.
The Peaks Island Land Preserve acquired the property in 1995, transforming this military structure into a public space for exploration and education.
Visitors can access Battery Steele via Casco Bay Ferry from Maine State Pier, following Welch Street, Prospect Street, Brackett Avenue, and Florida Avenue.
The concrete structure contains a network of dark corridors, flooded chambers, and numerous rooms that display remnants of art installations on their walls.
