Sigiriya - Home of Ravan?

Sigiriya is home to an ancient complex of gardens, fountains, caves, and the ruins of a palace built by King Kashyapa I, who ruled Sri Lanka from 477 AD to 495. During his reign, he relocated the capital to Sigiriya over security concerns. Sigiriya is also thought to be the home of Ravan (the main antagonist from Ramayana), and the site is also mentioned and described by Sir John Mandeville in “The Book of Marvels and Travels,” written in roughly 1350 AD.
