Rio Amarillo (Mayan site) — Wikipedia

Rio Amarillo also known as La Castellona or La Canteada, is an archaeological site of the Mayan civilization located in the department of Copan in Honduras that dates back to the Mesoamerican classical period. The structures found reveal that it was a city of big size and that functioned as a point of passage for Mayan travelers during their journeys, although it also shows the decline of the Mayan Civilization and it was the last Mayan city in Honduran soil to be abandoned by the end of the classic period.
