Cape North Lighthouse lens

This lighthouse, erected in 1908 at Cape North, Nova Scotia, is constructed of 32 cast-iron plates joined together
with bolts. It stood vigil over the Cabot Strait until 1980 when it was acquired by the Museum and moved to this site. The castiron plates of this lighthouse actually date back to 1856, when they were first assembled to serve as the tower of the famous landfall light at Cape Race, Newfoundland. When a larger lighthouse was built at Cape Race in 1908, the old tower was disassembled, taken by ship to Nova Scotia, and reused for the light at Cape North.

The sectional design of the tower was chosen in response to the challenge of constructing a lighthouse in a remote,inaccessible location using only local, unskilled labour. The checkerboard pattern served to distinguish this lighthouse from others, and ensured that the tower stood out against the often snow-covered landscape. The light was originally powered by coal oil while the large lens was turned by a clockwork mechanism. Both the light and the lens rotation system were eventually converted to electric power.
