King Kashyapa built his Sri Lankan fortress atop a monolith around 477-495 CE, hauling ~3 million clay bricks to the summit after usurping the throne. A hand-carved tank sits at the summit roughly 90 ft long, 68 ft wide, and nearly 7 ft deep, using percolation plus drainage to stay functional even during monsoons. The surrounding area shows signs of Mesolithic habitation ~5,000 years ago, and white marble blocks used in construction are not native to the area, their source still unknown. Pure ancient genius! 🏛️🪨
