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.

I’ve only seen lighthouses in pictures and paintings. I love how they look though. I also like old ships so I guess they go hand -in-hand. I bet I would enjoy learning more about their history too.
Wow–I’ve never heard of this lighthouse. Thanks not only for the photo but for the information, as well. What an interesting story, and a part of our history, too. Quite different from the lighthouses here on the Maine coast!
I had no idea this place was out there! That’s a good story. I’d like to see it.
I don’t know what it is but I just love lighthouses. I think they are so pretty and the history is just so interesting. I would love to see this one someday it sounds really amazing thanks for sharing and have a nice day.
I love visiting lighthouses and have visited some on Cape Cod and many on the Washington and Oregon coast. So fascinating and fun to learn about. I have never been to Mount Diablo but looks fascinating..
How far is it from the sea? Looks interesting.
As the crow flies, I would say maybe it is 30 miles or a bit less. But it is inland a ways in the east bay outside of San Francisco
I did not know about this lighthouse and i enjoyed learning its history. It would definitely be a place I would want to visit if I travel to California. It has an interesting shape and looks like the top has lightning rods beside the large searchlight.
How interesting, and that they still light it on that day so many years later attests to how important it was at the time.
