English to Portuguese Other Archaeology

The Nuraghe /nu'rage/ is the main typical archaeological monument of Sardinia.

It is typically a truncated cone tower, in the shape of a beehive, built with huge square blocks of stone, and usually located in a panoramic position. The monument has no foundations, and stands only due to the of the weight of stones, which may weigh as much as several tons. Some Nuraghes are more than 20 metres in height. Today, there are more than 8,000 Nuraghes in Sardinia, though it has been estimated that once the number was more than 30,000.
