What IS this?
If you guessed the inside of the 4 ton Fresnel lens that sits at the top of the landmark Hopetown lighthouse, you are correct.
Officially named the Elbow Reef Lighthouse, it is one of the last manually operated lighthouses in the world.
Its completion in 1864 provoked outraged protests by wreckers, sea salvagers and plunderers.
The light rotates once every 15 seconds and can be seen for 17 miles. During the day, as above, it is shrouded to prevent sun damage to the lens.
Here are the storage tanks, on a platform about halfway up the lighthouse, which hold the pressurized Kerosene it burns, with a wick and mantle, (made by Coleman, the camping equipment manufacturer).
A lighthouse keeper must wind the weights every two hours to keep it working.
The light is 89 feet off the ground.
And 120 feet above sea level, as it sits on a hill.
The inside is pink, with green stairs that spiral up the inside walls,
creating a nautilus effect.
There are windows along the staircase.
The last 20 steps are up a ladder.
And then you sort of limbo out a small, low opening onto a deck that rings the lighthouse just below the lens.
Look at this beautiful doorhandle for that little door.
A climb up its101 stairs is rewarded by a panorama of magnificent views. On the east side is Hopetown, its harbor, and, beyond that, the Atlantic Ocean:
The harbor entrance is to the north and east:
And to the west is the Sea of Abaco:
