Unveiling the Mysteries of Teotihuacán One of the greatest enigmas surrounding Teotihuacán is the identity of its builders. While it’s commonly attributed to the Teotihuacanos, little is known about these mysterious people. Teotihuacan boasts two monumental pyramids, the Pyramid of the Sun and the Pyramid of the Moon, both of which align with celestial events which leaves experts wondering how an ancient civilization managed to achieve such architectural feats with limited technology. The city’s meticulous urban planning is another puzzle and suggests a high level of organization and engineering prowess that remains a mystery. At its peak, Teotihuacán was housing an estimated 150,000 inhabitants. Yet, its abrupt decline and eventual abandonment around the 7th or 8th century AD remain unexplained. Teotihuacan’s intricate murals and temples provide glimpses into its religious practices, which were central to its culture. Their exact nature is still the subject of ongoing research and debate. Beneath the pyramids and structures, a network of mysterious tunnels and chambers has been discovered. Many remain unexplored.
