Speaking of Stone ...

Here is an arch from the gusuku at Zakimi.

This is a UN-recognized world heritage site. The original was built during the 15th century and, after its destruction by our 20th century's warfare, the walls were reconstructed.

Zakimi was built by the stonework genius, Gosamaru. Its signature feature is the keystone in the middle of the arch.

The views from the site are spectacular. It is open to the public and is located mid-island in the village of Yomitan.
