 An important part of the Mesoamerican religious system was replicating their beliefs in concrete tangible forms, in effect making the world an embodiment of their beliefs.This meant that the Mesoamerican city was constructed to be a microcosm, manifesting the same division that existed in the religious, mythical geography—a division between the underworld and the human world.The underworld was represented by the direction north and many structures and buildings related to the underworld, such as tombs, are often found in the city's northern half.
