The culture that built cities on mounds was the Chinese
Some mounds were constructed around important public structures, such as temples. A temple would be built, then after a generation, destroyed and covered with earth. Some mounds were created to house burials. Some, such as the Great Serpent Mound in Ohio, are astronomical observations and are aligned with equinoxes or solstices. Some are effigy mounds, that is they are sculpted into representational forms, such as a giant bird. Mounds can be sites of elite houses, council houses, and temples and would be protected from flooding from nearby rivers.
