 The Trincheras civilization is located in the village of Trincheras, Sonora, actually owes its name to the peculiar type of constructions, placed at different levels on the hill that is close to the village.It seems to be a center for gathering and trade used often by these ancient settlers; which is why it was inhabited almost permanently.The constructions in the shape of trenches, in addition to being the place of dwelling for the settlers -because of the security the height afforded and their design geared for defense- were also places for observation and the celebration of ritual ceremonies.
