According to the "Mahavamsa," they arrived in Sri Lanka during the reign of Devanampiya Tissa of Anuradhapura (307–267 BCE) who converted to Buddhism and helped build the first Buddhist stupas and communities. Tissa donated a royal park in the city to the Buddhist community, which was the beginning of the Mahāvihāra tradition. Mahinda is associated with the site of Mihintale, one of the oldest Buddhist site in Sri Lanka. Mihintale includes numerous caves which may have been used by the early Sri Lankan sangha.
