34 Forgotten Ancient Ruins That Deserve More Attention

15. Tulum, Mexico: A Seaside Stronghold of the Maya

Perched atop limestone cliffs that plunge dramatically into the turquoise waters of the Caribbean, Tulum is one of the most visually striking ancient ruins in the Americas. Unlike the sprawling jungle-bound metropolises of inland Maya civilization, Tulum’s setting is unmistakably coastal—built to command sea routes and gaze out over trade ships gliding along the Mesoamerican reef. Flourishing between the 13th and 15th centuries, Tulum was a major port, connecting maritime trade routes with inland cities like Coba. The site’s architecture reflects both functionality and spiritual depth. The Castillo, perched on the cliff’s edge, likely served as a lighthouse and ceremonial temple, guiding traders by both day and starlight. The Temple of the Frescoes holds remnants of vibrant murals depicting Maya gods and cosmology, showcasing the city’s dual role as both commercial hub and sacred site. Today, visitors can walk along the fortified walls, wander among temple ruins, and descend to the beach below for a rare chance to swim beneath a living piece of Maya history.
