El Castillo at Chichen Itza: A Maya Pyramid of Kukulkan

The majestic El Castillo pyramid stands tall under the sky's azure canvas dotted with wispy clouds in this ancient Mayan archaeological site located near the Yucatan Peninsula in Mexico. Its stepped sides ascend to a temple entrance flanked by stone columns that once supported an ornate roof now lost over time. This iconic structure is renowned for its astronomical alignments particularly during equinoxes when shadows cast create serpent-like patterns down one of its stairways, a testament to the advanced knowledge possessed by the Maya civilization.
