Rani ki Vav — a love letter carved underground. 1000 years ago, Queen Udayamati built this subterranean memorial for her king. Not above ground… but beneath the Earth. 7 storeys deep, 500 sculptures, cosmic symmetry and a cooling system that worked like natural AC long before the world discovered architecture textbooks. Centuries later, the Saraswati river flooded… the entire structure got buried under गाद (silt) — and that’s what actually preserved it. Today it stands as a UNESCO World Heritage
