El Caracol

Brief History: Known as “El Caracol” (The Snail), this round observatory was used by Maya astronomers to track stars, planets, and celestial events. Built around 906 AD, it shows how scientifically advanced the Maya were. Notable Features: The spiral staircase inside gives it its name. Windows in the upper dome align with key celestial bodies and seasonal changes, such as the setting sun during solstices and the planet Venus—sacred to the Maya. Fun Fact: The building’s astronomical accuracy rivals many modern observatories. Its design likely helped priests decide planting cycles, religious ceremonies, and more. Visitor Info: While partially collapsed, El Caracol is one of the most intellectually fascinating structures, especially for astronomy lovers.
