The Mayan ruins date back to various periods, with the earliest construction reaching as far back as 2000 BC. The height of Mayan civilization occurred during the Classic Period, roughly from 250 AD to 900 AD, when many of the most iconic structures were built, including temples, pyramids, and palaces.
After this period, many cities were abandoned or fell into decline, but some continued to be occupied until the Spanish conquest in the 16th century. As a result, the ruins we see today are remnants of a civilization that spanned over three millennia, showcasing the impressive architectural, astronomical, and cultural achievements of the Maya.
