Tokyo Tower vs Eiffel Tower
The Eiffel Tower in Paris, France was inaugurated in March 1889. It was built by 300 iron workers, one of whom was killed in the process, and has over 18,000 iron pieces (18,038 to be exact) and 2.5 million rivets. The Eiffel Tower is made of "puddled iron" and took 2 years and 2 months to complete.
The Eiffel Tower's original weight was in excess of 8,300 tons but 1000 tons was removed during renovation in the 1990s. It now weighs about 7,300 tons (the metal framework, not the extra additions for tourists).
The Tokyo Tower, in comparison, is made of steel and took the 400 steel workers only 18 months to complete from June 1957 to December 1958. One third of the steel in the Tokyo Tower comes from tanks that saw use in the Korean War of the 1950s.
The Tokyo Tower weighs 4,000 tons, almost half that of the Eiffel Tower. That's why it's considered great. It has also been built in one of the world's most active seismic cities, Tokyo, Japan, which experiences s1500 earthquakes a year (of usually diminutive magnitude),
Tokyo Tower looks more beautiful at night time with those lights but obviously the Eiffel Tower is more famous and older, and that makes it more impressive as an item / object in my opinion.
I like your summary about the relative weights of the towers. Is the steel used in the Tokyo Tower that much different to what would be used today? I see a big difference in the iron used in the Eiffel Tower compared to the steel of the Tokyo Tower - but what about today?
