2020—A Little Sparkplug

The Spring Point Ledge Lighthouse on the west side of southern approach to Portland Harbor is a sparkplug lighthouse. These unique kinds of lighthouses are round, cast iron structures usually three stories in height with the keeper’s quarters beneath the round lantern room. Because of their shape, these lighthouses have come to be called “sparkplugs.” Sparkplugs were prefabricated, brought to the site by barge, and put in place by floating cranes. The last one was erected in 1926. Spring Point Ledge Lighthouse was built in 1897. This image was taken using my Nikon 8-15mm fish eye lens. By keeping the horizon at the center of the frame, the curvature so characteristic of images taken with fish eye lenses is eliminated.
