This Buddhist Temple in Nara Japan is incredible. It is the largest human-made wooden structure.
When Japan was involved in World War II, there was concern that this Temple might be damaged by a bomb. The Japanese people decided to disassemble this temple. They loaded the pieces of wood onto railroad tracks that they built up to the structure and they stored all of the pieces until the war was over when they could rebuild the Temple safely.
There are no screws, nails or glue used in the construction of this Temple.
