7. Stony Point Lighthouse
Located at the Stony Point Battlefield Historic State Site, Stony Point boasts the title of the oldest lighthouse on the Hudson River. Built in 1826, only a year after the completion of the Erie Canal, the structure was used to mark the entrance to the Hudson Highlands, and to warn maritime navigators about the rocks of the Stony Point peninsula.
Although it was decommissioned in 1925, the thirty-foot-tall octagonal lighthouse was in service for nearly a century before it was officially acquired by the NYC Department of Parks and Recreation. Following its restoration in 1995, its light was reactivated and is now operated by solar power.
