Spanish farmers built massive stone monuments before the pyramids

Deep in the Spanish interior near Toledo, a 6,000-year-old necropolis reveals that early farmers were master architects long before the rise of the pharaohs. These prehistoric builders didn't just dig graves; they engineered a landscape of memory using massive stone slabs to create a 'city of the dead.' Constructing these monuments required a staggering investment of labor, as small communities had to coordinate hundreds of people to quarry, transport, and precisely position heavy stones using only primitive tools and sheer human willpower.
