I know, I've seen a few of those. Most of them are tiny replicas built ironically for the novelty factor. Besides the ones built for tourist traps, most are justified as radio towers. But as radio towers the design is laughably obsolete. Compare with guyed masts, which virtually every developed town and city around the world has numerous examples of.
That was a popular opinion when it was built. Eventually it became iconic, but nevertheless I don't see many cities rushing to build their own.
