The Maasai live in Kraals arranged in a circular fashion. The fence around the kraal is made of acacia thorns, which prevent lions from attacking the cattle.
The Maasai believe in one God, whom they call Ngai. Nagi is neither male nor female. Many of the Maasai beliefs involve or are centered around cattle. For more information, go to http://www.bluegecko.org/kenya/tribes/maasai/beliefs.htm
