One of the most visually stunning Inca ruins is at Moray, an
archaeological site in Peru approximately 50 km northwest of
Cuzco and just west of the village of Maras. In a large bowl-
like depression, is constructed a series of concentric terraces
that looks like an ancient Greek amphitheater. The largest of
these terraces are at the center – they are enormous in size,
and descend to a depth of approximately 150 meter, leading to a
circular bottom so well drained that it never completely floods,
no matter how plentiful the rain. The concentric terraces are
split by multiple staircases that extend upward like spokes of a
wheel and enable people to walk from the top to the bottom of
the bowl. Six more terraces, in connected ellipses rather than
perfect circles, surround the concentric heart of Moray, and
eight terraced steps that cover only a fraction of the perimeter
overlook the site. The purpose of these depressions is
uncertain, but the most widely agreed theory is they used to
