many decommissioned lighthouses have survived destruction, and in
some cases have even returned to performing their original functions.
The Three Sisters - three towers built together , originally at
Nauset Beach on Cape Cod, Massachusetts, were destroyed by erosion.
A few years prior to the 20th century, they were replaced by three
wooden towers that served the area until shortly after the First
World War, when they were sold off to multiple parties to be incorporated
into private summer cottages. Recently, they were acquired by the
National Park Service and relocated again, this time near their
many lighthouse structures have been destroyed or dismantled, many
of their components, especially those with Fresnel lenses, have
been preserved and relocated so they may continue to be appreciated.
Some lenses have been interned in museums, such as the one taken
from the Sambro Island Lighthouse that now resides in the Maritime
Museum of the Atlantic in Halifax, Canada. Similarly, the lantern
from the Table Bluff Lighthouse, which has long been gone due to
erosion, now sits atop a memorial lighthouse structure near a marina
in Eureka, California.
