Just about 23 miles west of Austin, tucked away in the Hill Country of USA, lies a natural wonder that looks like something out of a fantasy film. Hamilton Pool Preserve isn’t just a swimming hole—it’s a collapsed grotto that gave birth to a shimmering turquoise pool, surrounded by mossy limestone cliffs and a curtain of falling water. Yeah, it’s as magical as it sounds.

Picture this: rows upon rows of human skulls stacked neatly on wooden racks, bleached by the sun, staring out into the sacred courtyards of ancient Tenochtitlan. This isn’t a scene from a horror movie — it’s history. Meet the Tzompantli, one of the most chilling and misunderstood relics of Aztec civilization.
