The Ise Grand Shrine has been demolished and rebuilt over sixty times. Same design, new wood, every two decades.
Why? Because the building isn't the point. The knowledge is.
Each rebuild trains the next generation of carpenters. The skill survives by being used, not preserved. A museum piece dies the moment its last maker forgets.
Permanence through renewal, not through stone. The thing lasts because it's remade — not despite it.
