Built during the Mauryan dynasty by King Ashoka in 249 BCE, this ancient Indian architectural brilliance was constructed as a Buddhist pilgrimage and is located in the Uttar Pradesh. The cylindrical shaped Stupa finished with red bricks and stones is believed to be the spot where Lord Buddha first preached his sermon to his five believers after getting enlightenment in Bodh Gaya and is thus visited by thousands of devotees from around the world.
