An oddly interesting mystery. I could imagine a culture deciding that there is some worthy symbolic value in renewal by fire. In Japan there is the Ise Grand Shrine which is torn down and rebuilt every 20 years since year 692. The design is unique, specified exactly and never changes so it is always both ancient and freshly new. https://en.wikipedia.org/wiki/Ise_Grand_Shrine https://en.wikipedia.org/wiki/Ise_Grand_Shrine
