According to historical records, it was said that King
Ashoka, in his reign on BC 268 to 232, had sent his counselors to the whole region to establish numerous
stupas to honour the eighty-four thousand relics of the Buddha. Shwe Let Hla stupa was one of the stupas which was built by the counselors of the King Ashoka in Yan Aung Myin village; formerly called Naung-Pyin village. It was also considered that, on AD 87, the King
Thamoddarit (called later Bagan King) arrived at the stupa hill and maintained Naung-Pyin Stupa. When his hand was badly injured during a war with a Phyu kingdom, he retreated his troops and camped near the pagoda. Besides, he made a wish at the stupa to heal his wound instantly and to win the victory against his enemy. After witnessing that his prayers came true and were fulfilled miraculously, he changed the title of 'Naung Pyin Stupa' into 'Yan Aung Myin Stupa' (lit. Victory against foe) and renamed Naung Pyin village as Yan Aung Myin village. Since the injury of his arm had been healed and reached to a good condition in a blink of an eye, he named the pagoda 'Lett -Hla Pagoda', (lit. Beautiful hand or good hand) and later known as "Shwe Lett Hla Pagoda". ==Maintenance==
