This lighthouse originally operated at Cape Race, Newfoundland, from 1856 to 1907. In 1908 it was dismantled and moved to Money Point at Cape North on Cape Breton Island, when it remained in service until 1980. The first lighthouse in Canada was erected on Cape Breton Island, at Louisburg in 1731. - Function

Unknown - Technical
-
Technologically very interesting, being of cast iron, modular construction, a 19th c. technique which was suited to the circumstances & location. Beacon machinery altered for museum use, but many traces of the original clock-work and oil-burning technology employed to operate the light remain. Revolving and flashing systems of light were introduced around the end of the 18th century to help distinguish one lighthouse from another. By 1890 the revolving light mechanisms were floated in mercury and driven by clockwork with great weights, which were wound up by the keeper at 2- to 4-hour intervals. The mercury floating system allowed bigger lamps to be used without having the friction problem. - Area Notes
