Mihinthale is a big rock located near Anuradhapura town. According to an ancient Sinhalese book called Mahawanshaya Buddhist monk named Mihindu who came to Sri Lanka to teach Buddhist Philosophy had met King Devanampiyatissa on this mountain top. And then
Monk introduced Buddhism to the country. Monk Mahinda impressed the King with the peacefulness of the Buddhist doctrine and his satisfied, peaceful nature. King rejected the War and spread Buddhism to the nation and he has built a temple to worship.
Still, Buddhist people are going there to worship and also foreigners have a special attraction towards Mihinthale due to two reasons, because of its historical value and also because of the nature of the mountain. Sri Lankans most important poya say called Poson is mainly celebrating due to the story of Mihinthale
