Sean Carroll had an interesting podcast recently https://www.preposterousuniverse.com/podcast/2019/08/19/60-lynne-kelly-on-memory-palaces-ancient-and-modern/ https://www.preposterousuniverse.com/podcast/2019/08/19/60-l... where the guest put forward the theory that a lot of prehistoric monuments (e.g. Stonehenge) were actually memory palaces https://en.wikipedia.org/wiki/Method_of_loci https://en.wikipedia.org/wiki/Method_of_loci which the builders used to remember all their cultural knowledge.
