Mount Diablo Lighthouse in California

It is not often that you find a lighthouse on dry land but when you visit Mount Diablo in Concord, California, you can see a a lighthouse that was used for many years before 1941 as a beacon for pilots and ships in the San Francisco bay. It was used until December 7th, 1941; a day that has gone down in infamy and remembered in reverence for the attacks on Pearl Harbor.

Since then, the lighthouse has been dark for fear of lighting the way for more attacks on our soil. That is, except for every December 7th, when it shines from dusk till dawn. This cool lighthouse stands as a memory for pilots and sailors alike and can be toured when you take a trip to the top of the mountain.
