King Kashyapa built Sigiriya as his capital during his 477–495 CE reign, after deposing Dhatusena. Around 3 million bricks were hauled up the rock. A granite tank at the summit measures roughly 90 by 68 ft and nearly 7 ft deep; estimates put the excavated stone above 3,500 tons. Its collection and overflow-drainage system was designed to cope with monsoons. Evidence at nearby Aligala reaches back nearly 5,000 years, while the source of the site's white marble remains uncertain. The video compares scoop-like marks in the tank with Egyptian and Peruvian megalithic sites; that is the presenter's interpretation, not a demonstrated link. Sigiriya later served as a Buddhist monastery until the 14th century, and Major Jonathan Forbes encountered and recorded the ruins on horseback in 1827. A striking feat of ancient engineering. 🏛️🪨

Key facts
- Evidence from the Aligala rock shelter indicates occupation nearly 5,000 years ago.
- Kashyapa ruled from 477 to 495 CE and built Sigiriya after deposing Dhatusena; 473 CE was not the start of his reign.
- About 3 million clay bricks are estimated to have been used and hauled up the rock; no ancient construction stairway has been identified.
- White marble was used in the complex, but no definite source is established.
- The summit tank is described as about 90 ft long, 68 ft wide and nearly 7 ft deep; estimates put the excavated granite at more than 3,500 tons.
- The video says the tank has scoop-like marks rather than obvious chisel marks and compares them with megalithic sites in Egypt and Peru; that comparison is the presenter's interpretation, not a demonstrated common technique.
- Water collection, percolation and overflow drainage helped the tank cope with monsoon rain.
- After Kashyapa, Sigiriya became a Buddhist monastery and remained in monastic use until the 14th century.
- Major Jonathan Forbes encountered and recorded the ruins on horseback in 1827.
