This realistic photograph captures the Pyramid of Kukulkan, the core landmark of Chichen Itza on Mexico's Yucatan Peninsula, one of the most representative Mayan relics and a World Cultural Heritage site. Under the cloudless deep blue sky, warm golden sunset light slants on the pyramid's stone steps, casting distinct shadows that highlight the profound historical sense of the ancient architecture. Standing on open grassland with tropical forests as dark background, the scene is magnificent and full of mysterious ancient civilization vibe. The famous light-and-shadow serpent phenomenon appears here during equinoxes, reflecting Mayans' outstanding wisdom in astronomy.
