Inca Technology
Most Inca buildings
are rectangular in plan, have stone foundations, and stone or adobe upper
walls. Some structures, such as this one from Machu Picchu, have interior
niches in the walls; many lack such ornamental detail. Entrance to
buildings is provided through a doorway or doorways symmetrically placed on
one of the long walls. Because it is a relatively large structure, this
building has two doorways, rather than the more common single entrance.
