Historic Engineering Wonders: Photos That Reveal How They Pulled It Off

This article seems to focus mainly on Western civilization. Not saying they aren't wonders. There were many engineering feats in the South/East Asian subcontinents that are not covered.

The article lists a "Snake Bridge on the Macclesfield Canal". Here's a spiral bridge on that canal, but not the same one:

Fascinating! I would buy this in a "coffee table" style book.

Cool to see how much engineering relied on intuition and improvisation before modern tools existed. These methods look primitive now, but they worked because people understood materials so well. Makes me wonder how much of that hands-on knowledge we’re losing today.
