Stonehenge in the Amazon!!

Archaeologists with the Amapa Institute of Scientific and Technological Research said they uncovered the ruins near Calcoene, 390 kilometers (240 miles) from Macapa, the capital of Amapa state, near Brazil's border with French Guyana.

"Only a society with a complex culture could have built such a monument," archaeologist Mariana Petry Cabral, of the Amapa Institute of Scientific and Technological Research (IEPA)

The pre-colonial observatory was built of 127 blocks of granite each three meters (10 feet) high, arranged upright and evenly spaced in circles in an open field. The archaeologists do not know yet when the structure was built, but ceramic fragments found nearby suggest that it is between 500 and 2,000 years old.

Researchers are comparing the discovery to Stonehenge, a mysterious stone circle in southern England that was built between 3000 and 1600 BC
