  In the Upano River valley of eastern Ecuador, several cities were established by the Upano and Kilamope cultures around 500 BCE. The cities in the Upano Valley consisted of agricultural societies that cultivated crops such as corn, manioc and sweet potato. The cities fell into decline around 600 CE.
