What was unusual about the wall built around the center of Great Zimbabwe?

Question

A. It was made of wood.
B. It was very short.
C. It was built in a circle.
D. It used no mortar.

Answer 1

The answer is 'D'. This complex of ruins from which the modern nation of Zimbabwe took its name is one of the country's greatest historical and cultural attractions. Great Zimbabwe, the largest ruins in Africa, covers almost 1,800 acres.

Sited on an open wooded plain surrounded by hills, the ruins comprise the vast Great Enclosure complex, and on a nearby kopje the Hill Complex, a veritable castle of interlocking walls and granite boulders, while all around in the valley lie a myriad other walls. The ruins feature an array of chevron, herringbone and many other intricate patterns in its walls, and the astonishing fact is that despite the dry-stone technique used in Great Zimbabwe's construction (no mortar binds the stone blocks), the complex has endured for seven centuries.
