Ancient Engineering: “Miyadaiku” wood joints

In Asia, we have wooden architectures that have been standing for thousands of years, some of which are still open to the public.

“Miyadaiku” is a name for Japanese carpenters, who are known for their practice of using complex and elaborate wooden interlocking methods to construct Japanese shrines and temples. In the old days, our ancestors probably knew that they would need to repair the architecture due to constant war, natural disasters, or rotting of a piece of wood, they designed the architecture to be disassembled.

These wooden locking methods do not need to use a single piece of nail to combine the architecture together, surprisingly making it more resistant to earthquakes. (https://www.youtube.com/watch?v=w78Yb_aotH0)
