🏆 Admiral Peary’s Island — Private island home of Arctic explorer Robert Peary — who claimed to reach the North Pole in 1909
Eagle Island State Historic Site preserves the summer home of Admiral Robert E. Peary (1856–1920) — the Arctic explorer who claimed to be the first person to reach the North Pole on April 6, 1909 (though this claim remains disputed). The island in Casco Bay features Peary’s stone house, taxidermy collection from Arctic expeditions, and stunning views of Casco Bay and the open Atlantic. Peary designed the house with two massive fireplaces and walls embedded with Arctic quartz crystals — creating a mini-museum of polar exploration.
