My Seven Wonders of the World, #7: Walls of Osaka Castle
Osaka Castle is an interesting construction in its own right, and is surrounded by gardens and dry and wet moats making it a pleasant park in the center of Japan’s second-largest city. My focus in this designation are the fitted-stone walls surrounding the enclosure and central tower.
Almost five hundred years old, the walls are dry stacked of large square stones, some at the corners and gates huge, with smaller stones fitted to add stability. A rigid wall construction would not serve in earthquake-prone Japan. Must be seen (as we did in 1985) to be appreciated.
What we see today is a re-construction of the ancient walls and castle, which was destroyed several times over the centuries. The layout of the walls, moats and gates facilitated defense in the age before effective long-range artillery.
This last wonder is a place holder for the great stone works of ancient Asia. Elsewhere in Japan I saw similar stacked stone walls. In addition to their function as rock chutes for defense, the curves pull the eye upward, contributing to the wonder of their sites. I have not seen the Great Wall of China (itself mostly a re-construction), but would like to.
