| 説明 | This is the original 1st order fresnel lens. It was removed from the lantern in 2011 and is now displayed in the adjacent fog signal building. The lantern itself is bad shape and it was necesssary to remove the lens in order to protect it as well as begin the work to stabilize the badly deteriorating lantern. |
