Passage Island Lighthouse (far right) is located on a small island, off the east coast of Isle Royale (right-click image to enlarge).
The light tower is 44 feet (13 m) high, constructed of field stone, and is square on the first level, transitioning to octagonal above.[4] It is topped with a ten-sided cast iron lantern, accessible via a spiral staircase within the tower.[4] The tower is integral with the keeper's house, which is a two-story field stone house measuring 26 by 30 feet (7.9 by 9.1 m).[4]
History
The need for a lighthouse between Passage Island and Isle Royale was recognized as early as the 1860s, as lake traffic increased dramatically due to the upsurge in mining in the Upper Peninsula.[4] However, it took until 1875 before Congress authorized funds for the construction of a lighthouse.[4] However, because of Congress's desire to bring political pressure to bear on the Canadian government to force them to build a lighthouse in Lake Erie, the appropriated $18,000 for Pasage Light was not released until 1880.[4] Construction began in 1881, and the light was completed the following year.[4] A fog signal was added in 1884, and in 1894 a new flashing white lens manufactured by Barbier, Benard & Turenne of Paris was installed.[4]
In 1978, the station was automated, and in 1989 a 7.5-inch (190 mm) acrylic lens was installed, replacing the Fresnel.[4]
