In my opinion the Gateway Arch is one of the Seven Man-Made Wonders of the USA and Canada. Old Water Tower, Chicago - one of the few buildings to survive the great fire of 1871. Renaissance Centre, Detroit, Michigan. Skyscrapers in cities such as New York City, Chicago and San Francisco. The world's first skyscraper was built in Chicago in 1885.
Many skyscrapers have observation decks open to the public.
Space Needle, Seattle, Washington State. Statue of Liberty, New York City. Stratosphere Tower , Las Vegas. While I have an interest in the subject of towers and tall buildings, I am not an expert. Therefore I regrettably cannot offer any information on the subject other than that which appears on these pages.
