14. The Walls Were Almost as High as a Four-Story Building
The famed Theodosian Walls, which were a marvel of early engineering and construction, were truly unimaginably high, especially for the era.

Typically, a story of a building is roughly calculated as 10 feet, so the walls around Constantinople were virtually four stories high. It’s no wonder they survived so many sieges!
