Did you know Alexander the Great’s bestie, Hephaestion, might have a tomb that lights up with sunlight every winter solstice? A new study says the massive Kasta monument in Greece was possibly built to flood with sunlight on December 21, symbolizing renewal and cosmic power. Some historians aren’t totally convinced, but if true, that’s some next-level friendship goals (and ancient engineering flex). Imagine your tomb designed to catch the perfect winter glow! #HistoryMystery #AncientGreece #AlexanderTheGreat #Culture
