Sanchi Stupa, also written Sanci, is a Buddhist complex, famous for its Great Stupa, on a hilltop at Sanchi Town in Raisen District of the State of Madhya Pradesh, India. It is located in 46 kilometres (29 mi) north-east of Bhopal, capital of Madhya Pradesh. The Great Stupa at Sanchi is one of the oldest stone structures in India, and an important monument of Indian Architecture. It was originally commissioned by the emperor Ashoka in the 2nd century BCE. Its nucleus was a simple hemispherical brick structure built over the relics of the Buddha. It was crowned by the chhatri, a parasol-like structure symbolising high rank, which was intended to honour and shelter the relics.
