Battery Duane
Fort Wadsworth
Crumbling over time, these concrete platforms mark where large guns once guarded New York Harbor. In the late 1800s, a Glacis Mortar Battery – once located just beyond these ruins – could lob projectiles onto enemy ships entering the Narrows below, although no vessels ever dared.
Battery Duane, built here in 1895-97 as part of the Endicott Coastal Defense System, replaced the mortar battery with five 8-inch-diameter rifled guns. Mounted on “disappearing” carriages, these cannon recoiled behind this concrete wall when fired.
Within ten years, longer-range weapons outdated Battery Duane’s guns and they were removed in 1915. Today, only these broken walls remain.
