This dagoba (arguably the largest at Mihintale) is thought to have been built to house relics of Mahinda. The bodhi tree to the left of the base of the steps is said to be one of the oldest surviving ones. From here there is a view over the lakes and trees to Anuradhapura, a horizon studded with the domes and spikes of all the massive dagobas.
A small temple at the foot of the dagoba has a reclining Buddha and Technicolor modern frescoes – donations are requested. A room at the side is a devale (a complex designed for worshipping a Hindu or local Sri Lankan deity) with statues of major gods – Ganesh, Vishnu, Murugan (Skanda) and Saman.
