A bird-cage lantern was the style of lantern common to American lighthouses in the early years of the nineteenth century. The lanterns received their name because of their appearance; they are shaped like wire bird cages.
When Fresnel lenses were introduced to the country in the 1850s, most lighthouses were retrofitted with new lanterns, as the older ones could not support the new style of lens. Consequently, only four lighthouses with original bird-cage lanterns survive in the United States; those that do were discontinued before they could be fitted for the new lantern.

Famous quotes containing the word lantern:
“... It may be Prester Johns balloon
Or an old battered lantern hung aloft
To light poor travellers to their distress.
She then: How you digress!”
