Adolphustown is a geographic area located in Greater Napanee, Ontario, Canada, at on the Adolphus Reach of the Bay of Quinte in Lake Ontario. It was founded in 1784 by United Empire Loyalists. The original Loyalist Landing site is now the 74-acre (300,000 m2) U.E.L. Heritage Centre & Park, a museum, public park, and family campground.
Adolphustown was named for Prince Adolphus, Duke of Cambridge, a son of George III. A number of Quakers settled in this area in 1784 and held their first Monthly Meetings in Canada here.
The Old Hay Bay Church, built by United Empire Loyalist settlers in 1792 and the oldest Methodist building in Canada, was designated a National Historic Site of Canada.[1][2] It is open during the summer.
