Back on the road leading to Old Rd and outside the site proper are the remains of a monastery enclosed in the ruins of a stone wall. Inside are two dagobas, the larger known as Indikatu Seya (Dagoba of the Needle). Evidence suggests that this monastery was active in fostering Mahayana Buddhism. The main dagoba’s structure differs from others in Mihintale; for example, it’s built on a square platform.
Nearby is a hill that’s been dubbed Rajagirilena (Royal Cave Hill) after the caves found here with Brahmi inscriptions in them. One of the caves bears the name of Devanampiya Tissa. A flight of steps leads up to the caves.
