Question

mention the places where the stupas built by Ashoka were existed​

Answer 1

Stupa is a hemispherical structure containing Buddhist relics and place of meditation used by Buddhists monks. In the period between the Mauryas and the Guptas the older stupas were greatly enlarged and beautified. Of these three are noteworthy—those at Bharhut and Sanchi in Madhya Pradesh, and at Amaravati in the lower Krishna valley.
