Kaimanawa Wall

Some 30 kilometers south of Lake Taupo, in New Zealand, stands an enigmatic array of stone blocks. It "looks" like a wall; a human-built wall. It also "looks" old; perhaps 2,000 years old according to some. Who built it?

The stones that make up the wall are 4-ton blocks of ignimbrite, a soft volcanic rock that could have been easily dressed with stone tools. The four visible stones in the front wall were a uniform 1.6 metres tall, and 1 metre wide.

Nobody knows the true origins of this wall and many believe it nothing more than a natural phenomenon.
