Stonehenge, Wiltshire, England

---

We see here the most continuously undamaged portion of the circle. In true carpentry fashion, each vertical stone has two carved protrusions on its top, and each horizontal stone has a carved out recesses designed to mate with the appropriate protrusions. This mortise-and-tenon technique is the reason many parts of Stonehenge have remained intact through the ages. The carving was done with stones as tools; quite remarkable in and of itself.
