Sanchi Stupa 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 about 23 kilometres from Raisen town, the district headquarters and northeast of Bhopal, capital of Madhya Pradesh.

The Great Stupa at Sanchi is one of the oldest stone structures in India, and an important monument to the historical architecture of India.Buddhist Art Frontline Magazine 13–26 May 1989 It was originally commissioned by the Mauryan emperor Ashoka in the 3rd century BCE. Its nucleus was a simple hemispherical brick structure built over the relics of the Buddha. It was crowned by the chatra, a parasol-like structure symbolising high rank, which was intended to honour and shelter the relics. The original construction work of this stupa was overseen by Ashoka, whose wife Devi was the daughter of a merchant of nearby Vidisha. Sanchi was also her birthplace as well as the venue of her and Ashoka's wedding. In the 1st century BCE, four elaborately carved toranas (ornamental gateways) and a balustrade encircling the entire structure were added. The stupa at Sanchi, built during the Mauryan period, was made of bricks. The complex flourished until the 11th century.

Sanchi is the centre of a region with a number of stupas., all within a few miles of the site, including Satdhara (9 km to the W of Sanchi, 40 stupas, the Relics of Sariputra and Mahamoggallana, now enshrined in the new Vihara, were unearthed there), Bhojpur (also called Morel Khurd, a fortified hilltop with 60 stupas) and Andher (respectively 11 km and 17 km SE of Sanchi), as well as Sonari (10 km SW of Sanchi).Buddhist Landscapes in Central India: Sanchi Hill and Archaeologies of Religious and Social Change, c.

Overview The monuments at Sanchi today comprise a series of Buddhist monuments starting from the Mauryan Empire period (3rd century BCE), continuing with the Gupta Empire period (5th century CE), and ending around the 12th century CE. It is probably the best preserved group of Buddhist monuments in India. The oldest, and also the largest monument, the Great Stupa also called Stupa No. 1, initially built under the Mauryans, and adorned with one of the Pillars of Ashoka. During the following centuries, especially under the Shungas and the Satavahanas, the Great Stupa was enlarged and decorated with gates and railings, and smaller stupas were also built in the vicinity, especially Stupa No.2, and Stupa No.3.

Simultaneously, various temple structures were also built, down to the Gupta Empire period and later. Altogether, Sanchi encompasses most of the evolutions of ancient Indian architecture and ancient Buddhist architecture in India, from the early stages of Buddhism and its first artistic expression, to the decline of the religion in the subcontinent.

Mauryan Period (3rd century BCE)

The "Great Stupa" at Sanchi is the oldest structure and was originally commissioned by the emperor Ashoka the Great of the Maurya Empire in the 3rd century BCE.World Heritage Monuments and Related Edifices in India, Volume 1 p. 50 by Alī Jāvīd, Tabassum Javeed, Algora Publishing, New York Its nucleus was a hemispherical brick structure built over the sacred relics of the Buddha, with a raised terrace encompassing its base, and a railing and stone umbrella on the summit, the chatra, a parasol-like structure symbolizing high rank.Marshall, "A Guide to Sanchi" p. 31The Butkara Stupa is an example of such a hemispherical stupa structure from the Maurya period, that was extensively documented through archaeological work The original Stupa only had about half the diameter of today's stupa, which is the result of enlargement by the Shungas. It was covered in brick, in contrast to the stones that now cover it.

According to one version of the Mahavamsa, the Buddhist chronicle of Sri Lanka, Ashoka was closely connected to the region of Sanchi. When he was heir-apparent and was journeying as Viceroy to Ujjain, he is said to have halted at Vidisha (10 kilometers from Sanchi), and there married the daughter of a local banker. She was called Devi and later gave Ashoka two sons, Ujjeniya and Mahendra, and a daughter Sanghamitta. After Ashoka's accession, Mahendra headed a Buddhist mission, sent probably under the auspices of the Emperor, to Sri Lanka, and that before setting out to the island he visited his mother at Chetiyagiri near Vidisa, thought to be Sanchi. He was lodged there in a sumptuous vihara or monastery, which she herself is said to have had erected.Marshall, "A Guide to Sanchi" p. 8ff Public Domain text

Ashoka pillar

A pillar of finely polished sandstone, one of the Pillars of Ashoka, was also erected on the side of the main Torana gateway. The bottom part of the pillar still stands. The upper parts of the pillar are at the nearby Sanchi Archaeological Museum. The capital consists in four lions, which probably supported a Wheel of Law,Buddhist Architecture by Huu Phuoc Le p. 155 as also suggested by later illustrations among the Sanchi reliefs. The pillar has an Ashokan inscription (Schism Edict) and an inscription in the ornamental Sankha Lipi from the Gupta period. The Ashokan inscription is engraved in early Brahmi characters. It is unfortunately much damaged, but the commands it contains appear to be the same as those recorded in the Sarnath and Kausambi edicts, which together form the three known instances of Ashoka's "Schism Edict". It relates to the penalties for schism in the Buddhist sangha:

The pillar, when intact, was about 42 feet in height and consisted of round and slightly tapering monolithic shaft, with bell-shaped capital surmounted by an abacus and a crowning ornament of four lions, set back to back, the whole finely finished and polished to a remarkable luster from top to bottom. The abacus is adorned with four flame palmette designs separated one from the other by pairs of geese, symbolical perhaps of the flock of the Buddha's disciples. The lions from the summit, though now quite disfigured, still testify to the skills of the sculptors.Marshall, "A Guide to Sanchi" p. 90ff Public Domain text

The sandstone out of which the pillar is carved came from the quarries of Chunar several hundred miles away, implying that the builders were able to transport a block of stone over forty feet in length and weighing almost as many tons over such a distance. They probably used water transport, using rafts during the rainy season up until the Ganges, Jumna and Betwa rivers.

Temple 40

Another structure which has been dated, at least partially, to the 3rd century BCE, is the so-called Temple 40, one of the first instances of free-standing temples in India.Buddhist Architecture, Lee Huu Phuoc, Grafikol 2009, p. 147 Temple 40 has remains of three different periods, the earliest period dating to the Maurya age, which probably makes it contemporary to the creation of the Great Stupa. An inscription even suggests it might have been established by Bindusara, the father of Ashoka. The original 3rd century BCE temple was built on a high rectangular stone platform, 26.52×14×3.35 metres, with two flights of stairs to the east and the west. It was an apsidal hall, probably made of timber. It was burnt down sometime in the 2nd century BCE.

Later, the platform was enlarged to 41.76×27.74 metres and re-used to erect a pillared hall with fifty columns (5×10) of which stumps remain. Some of these pillars have inscriptions of the 2nd century BCE. In the 7th or 8th century a small shrine was established in one corner of the platform, re-using some of the pillars and putting them in their present position.

Shunga period (2nd century BCE) On the basis of Ashokavadana, it is presumed that the stupa may have been vandalized at one point sometime in the 2nd century BCE, an event some have related to the rise of the Shunga emperor Pushyamitra Shunga who overtook the Mauryan Empire as an army general. It has been suggested that Pushyamitra may have destroyed the original stupa, and his son Agnimitra rebuilt it."Who was responsible for the wanton destruction of the original brick stupa of Ashoka and when precisely the great work of reconstruction was carried out is not known, but it seems probable that the author of the former was Pushyamitra, the first of the Shunga kings (184-148 BC), who was notorious for his hostility to Buddhism, and that the restoration was affected by Agnimitra or his immediate successor." in John Marshall, A Guide to Sanchi, p. 38. Calcutta: Superintendent, Government Printing (1918). The original brick stupa was covered with stone during the Shunga period.

Given the rather decentralized and fragmentary nature of the Shunga state, with many cities actually issuing their own coinage, as well as the relative dislike of the Shungas for Buddhism, some authors argue that the constructions of that period in Sanchi cannot really be called "Shunga". They were not the result of royal sponsorship, in contrast with what happened during the Mauryas, and the dedications at Sanchi were private or collective, rather than the result of royal patronage.

The style of the Shunga period decorations at Sanchi bear a close similarity to those of Bharhut, as well as the peripheral balustrades at the Mahabodhi Temple in Bodh Gaya.

Great Stupa (No 1)

During the later rule of the Shunga, the stupa was expanded with stone slabs to almost twice its original size. The dome was flattened near the top and crowned by three superimposed parasols within a square railing. With its many tiers it was a symbol of the dharma, the Wheel of the Law. The dome was set on a high circular drum meant for circumambulation, which could be accessed via a double staircase. A second stone pathway at ground level was enclosed by a stone balustrade. The railings around Stupa 1 do not have artistic reliefs. These are only slabs, with some dedicatory inscriptions. These elements are dated to circa 150 BCE, or 175–125 BCE. Although the railings are made up of stone, they are copied from a wooden prototype, and as John Marshall has observed the joints between the coping stones have been cut at a slant, as wood is naturally cut, and not vertically as stone should be cut. Besides the short records of the donors written on the railings in Brahmi script, there are two later inscriptions on the railings added during the time of the Gupta Period. Some reliefs are visible on the stairway balustrade, but they are probably slightly later than those at Stupa No2, and are dated to 125–100 BCE.Buddhist Architecture Huu Phuoc Le, Grafikol, 2010 p. 149 Some authors consider that these reliefs, rather crude and without obvious Buddhist connotations, are the oldest reliefs of all Sanchi, slightly older even than the reliefs of Sanchi Stupa No.2.
