Attanagalla Raja Maha Viharaya, an ancient temple, is surrounded by devotees and tourists alike. A special monument was built to commemorate King Siri Sangbo who sacrificed his head. The place where the king offered his head is in the temple. The Dagoba was built in the monastery. The people believe that Attanagalla was the place where King Siri Sangbo lived after he handed over his kingdom to his brother Gotabhaya (249-262). But some archaeologists argue that this is not the place, but its Hatthikuchi Devalaya in the Anuradhapura District.
This temple was built around AD. It was built by King Gotabhaya during 249-262 and was later completed by AD. Built by King Upatissa in 365-406. This is the only Vatadage left in Sri Lanka and the rest are ruins. The Attanagalla Rajamaha Vihara Watadage is currently maintained and preserved by the Department of Archeology of Sri Lanka.
