The Americas

Most of Aztec pyramids were constructed with very steep stair cases. On the tops of these structures would sometimes be temples. Pyramids were often sometimes used for things like religious gatherings and human sacrifices. This was a time that was very brutal for people and was very violent. People would often sacrificed or killed for sport. People could compete in sport and the loser of the match would be sentenced to death.

Materials used for the ancient Mexican people would vary. Often times construction for the common house structure would consist of wood, straw, stone, sand, lime and clay. For the roofs they would combine straw and lay it over the structure. Floors would either be dirt or stone. The size of these houses would depend on your economic status. There was often one cut out in the wall per home for the display of a religious symbol or artifact.
