Lighthouse trivia

I have posted earlier about Chennai's newest lighthouse, but this picture was too good to ignore, so I'm re-hashing some of the trivia around this lighthouse. 

It is the only lighthouse in India that has a triangular cross section (for the most part, at least). It is also the only lighthouse in India that has an elevator inside it. It's counterpart on the second point in the USA - the only lighthouse with an elevator - is called the Charleston Light, at Sullivan's Island, South Carolina. Incidentally, that is also a triangular building!
