Theme 1: Ancient monuments served multiple, evolving purposes
Commenters repeatedly stressed that sites like Stonehenge or cathedrals were not built for a single function but changed over time and served social, religious, political, and practical roles.
- “What's interesting is that it may have had multiple changing purposes during construction. It took 1500 years to be established in its current form. It's pretty likely (to me at least) that the purpose of the year 1 work was different from year 1500.” – cogman10
- “It wasn't 'for the view,' it was, in no particular order, and non‑exhaustively: To provide work; To serve as a reminder of the power and authority of the church; To glorify God; To make sure all the other nearby kingdoms were aware of how much cooler you are than them.” – theodric
- “All of this suggests something complex within the cultural mindset of the neolithic people … It's not just a stone circle used to predict/measure equinoxes or eclipses …” – PaulRobinson
Theme 2: Many monumental constructions were originally intended to be temporary
A frequent point was that iconic structures such as the Eiffel Tower, the Atomium, and World’s Fair pavilions were planned to be short‑lived but survived due to later utility or preservation efforts.
- “Furthermore: The Eiffel Tower was planned to be temporary, it only still stands because it was used as a radio tower.” – ralfd
- “>planned to be temporary Same for the Atomium in Brussels, Belgium.” – whythismatters
- “I realize that was tongue in cheek, but what I found more interesting is that is was only to stand for 20 years and was initially set to be demolished in 1909.” – irishcoffee
- “Since it was part of a World's Fair, it is unsurprising today that the Eiffel Tower was slated for demolition … all those buildings were … expected to be demolished quickly … because they were never intended for permanent habitation.” – ButlerianJihad
Theme 3: The idea of Stonehenge as a “prehistoric computer” is dubious or discredited
Several participants dismissed the notion that Stonehenge functioned as an ancient astronomical calculator, citing lack of evidence or recent research that refutes such claims.
- “The BBC does not actually claim that.” – bazoom42 (responding to the “prehistoric computer” headline)
- “Of course the the theory is wrong: > new investigations since the 1960s have discredited Hawkins' ideas.” – bazoom42
- “the idea is now widely discredited.” – PaulRobinson
- “I always wondered why this was never simulated, and I guess the answer is that it would not work.” – JoeDaDude (referring to Aubrey‑hole eclipse predictions)
