twin lights

This is a severe crop of an already low-resolution photo… so yeah, I know, don’t bite my head off.

Built in 1862 and decomissioned in 1949 when they were considered obsolete, the Twin Lights can be found about 4.5 miles south of the Sandy Hook lighthouse. Only 4.5 miles? I’m no expert, but that seems close–why so many lighthouses in such a small amount of space? Well, they mark the entrance to New York Harbor, which according to Wikipedia is “one of the most intricate natural harbors in the world” (and as such, required very careful navigation).

Note that the Twin Lights are not identical.
