“Skilled masons are facing the daunting task of identifying where each stone was placed in the wall. They must then put the famed curved stone walls that supported the foundations of the castle back together like a jigsaw puzzle.”

Recently, I saw a fascinating NHK documentary about how the design and construction of the curved walls (known as “mushagaeshi” in Japanese) helped many of the original walls remain standing while a larger percent of the the more recent, Meiji-period walls collapsed. More about that later.
