Nice to hear from you again...:-). It's been quite a time since you last
posted. That is a fascinating url, thank you very much. Are you
interested in towers, their architecture or construction, or is it the
turning of words into codes and symbols which you find
fascinating...like I do? I recently went to the Eiffel Tower for a
visit, it was very windy up there, but it was a lovely view over the
Seine and Paris. I also went up the Statue of Liberty, many years ago,
right to the very top of her head, when we were allowed to do so. I
believe that they have blocked that bit off now, due to fears of
terrorism. The construction there too, was really interesting.
If it is exploring cryptology and secret codes, you like, then there is
no place better to visit that I can think of than the National
Cryptological Museum. You don't have to visit it physically, if you
live far away, you can visit it on line.
see url: https://www.nsa.gov/about/cryptologic-heritage/museum/
or url: https://en.wikipedia.org/wiki/National_Cryptologic_Museum
for its history and contents.
If you are more interested in the application of secrecy and secret
codes, especially during World War 11, you can also visit Bletchley Park
here in England

And, of course no one can miss the story of Alan Turing who did a lot of
the mathematics for the creation of Colossus, the worlds first
programmable computer, and which helped so much with shortening the war,
by breaking German codes and cyphers...so saving many lives.
For the maths and numbers game,
see url: http://www.turing.org.uk/
and url: https://en.wikipedia.org/wiki/Alan_Turing
I have been to Bletchley Park too, on a couple of occasions, and, on one
occasion was shown around the Colossus computer, by one of the original
Post Office team who built it, which was led by Tommy Powers.
