Ashoka established the original Great Stupa at Sanchi, while later dynasties transformed it into the magnificent monument visible today.
Standing on a peaceful hilltop in Madhya Pradesh, the Buddhist monuments of Sanchi are among the most important surviving monuments of ancient India. At their center is the magnificent Great Stupa (Stupa No. 1), associated with Emperor Ashoka and the early development of Buddhist architecture and art.
Sanchi is particularly important because it preserves nearly 1,400 years of Buddhist architectural history, from the Mauryan period in the 3rd century BCE through the Gupta period and into the early medieval period. UNESCO describes it as one of the oldest surviving Buddhist sanctuaries and a major center of Buddhism in India.
When was Sanchi Stupa built?
The original Great Stupa was commissioned during the reign of Emperor Ashoka of the Mauryan Empire in the 3rd century BCE, generally placed in the period after Ashoka's conversion to Buddhism.
It is important, however, to understand that the Sanchi Stupa that visitors see today is not entirely the original Ashokan structure.
The original monument was a comparatively simple hemispherical brick stupa. Over the following centuries it was enlarged, strengthened and decorated by successive dynasties. UNESCO identifies the main stages as follows.
| Period | Major contribution |
|---|---|
| Mauryan, 3rd century BCE | Original stupa and Ashokan pillar |
| Shunga, 2nd–1st century BCE | Enlargement of the stupa, stone facing, terraces and railings |
| Satavahana period, 1st century CE | Elaborate sculptural decoration of the four gateways |
| Gupta period, c. 5th century CE | Shrines and further architectural additions |
| Later centuries | Monasteries, temples and other Buddhist structures |
Thus, it is more accurate to say:
Ashoka established the original Great Stupa at Sanchi, while later dynasties transformed it into the magnificent monument visible today.
Who built Sanchi Stupa?
The foundation of the Great Stupa is traditionally associated with Emperor Ashoka (Aśoka), the great Mauryan ruler who reigned in the 3rd century BCE.
Ashoka played a crucial role in the expansion of Buddhism across the Indian subcontinent. At Sanchi he established a stupa and also erected one of his famous polished sandstone pillars.
The site itself was strategically important because it lies close to Vidisha, an important ancient city. Buddhist tradition also associates the area with Devi, Ashoka's wife, who is traditionally said to have been connected with Vidisha.
Ashoka and Buddhism
Ashoka's relationship with Buddhism is one of the most fascinating chapters of ancient Indian history.
After the devastating Kalinga War, Ashoka became increasingly committed to Dhamma and Buddhist ideals. He supported Buddhist institutions and helped Buddhism spread far beyond the territories of the Mauryan Empire.
Sanchi became one of the important centers associated with this process.
According to Buddhist tradition, Mahinda (Mahendra), Ashoka's son, was associated with the Buddhist mission to Sri Lanka and is said to have stopped in the Sanchi/Vidisha region before travelling to Sri Lanka. UNESCO notes the connection between Sanchi and this Buddhist missionary tradition.
What is a Buddhist Stupa?
The word stupa refers to a mound or monument associated with Buddhist sacred remains.
Stupas developed from ancient Indian funerary and commemorative traditions. In Buddhism they became particularly important because they could contain relics associated with the Buddha or important Buddhist disciples.
The stupa therefore became much more than an architectural structure—it became a focus of devotion, remembrance and pilgrimage.
The Great Stupa at Sanchi follows this basic concept.
Its enormous hemispherical dome represents the traditional stupa form, while the surrounding railings and gateways create a sacred space for ritual movement.
Architecture of the Great Stupa
The Great Stupa is an excellent example of the mature form of early Indian Buddhist architecture.
Its principal components include:
1. The Anda
The enormous hemispherical dome is called the anda.
It represents the basic mound-like form of the stupa and encloses the sacred space associated with Buddhist relics.
2. Harmika
At the top of the dome is a small square enclosure known as the harmika.
It represents a sacred enclosure and forms the base for the ceremonial umbrella structure.
3. Chhatra
Above the harmika rises the chhatra, or umbrella.
The umbrella was a symbol of honour and protection and became an important feature of Buddhist stupa architecture.
4. Medhi
The circular terrace surrounding the dome provides space associated with ritual circumambulation.
5. Vedika
The stone railing surrounding the stupa is called the vedika.
It separates the sacred area from the surrounding space while also defining the path followed by pilgrims.
6. Pradakshina patha
One of the most important features is the circumambulatory path.
Buddhist devotees traditionally walk around the stupa in a clockwise direction, keeping the sacred monument on their right.
This ritual is called pradakshina or circumambulation.
UNESCO specifically identifies the circular terraces, ambulatories, railings, harmika, yashti and chhatra as characteristic elements of the mature Indian stupa. (UNESCO World Heritage Centre)
The Four Famous Toranas
Perhaps the most spectacular feature of Sanchi is its four monumental gateways, or toranas.
They face the four cardinal directions:
North
South
East
West
The gateways were added centuries after Ashoka's original stupa and are famous for their extraordinarily detailed stone carvings.
The toranas are masterpieces of early Indian sculpture.
They depict:
Buddhist stories
Jataka tales
Animals
Trees and plants
Elephants
Lions
Horses
Yakshas and yakshis
Royal processions
Pilgrims
Sacred symbols
Scenes associated with the Buddha's life
The extraordinary carving on these gateways makes Sanchi one of the greatest surviving examples of early Indian narrative sculpture. UNESCO considers the proportions and sculptural richness of Stupa 1's four gateways an outstanding artistic achievement. (UNESCO World Heritage Centre)
Why isn't Buddha shown as a human figure?
This is one of the most interesting aspects of Sanchi.
If you look carefully at the early sculptures, you will notice something surprising:
The Buddha is generally not represented in human form.
Instead, artists used symbols to represent important events in his life.
For example:
| Symbol | Meaning |
|---|---|
| 🌳 Bodhi Tree | Enlightenment |
| ☸️ Dharma Wheel | Buddha's teaching/Dharma |
| 🐎 Horse | Great Renunciation |
| 🦶 Footprints | Presence of the Buddha |
| 🪷 Lotus | Purity and spiritual awakening |
| 🛞 Wheel | Teaching of Dharma |
| 🏛️ Stupa | Buddha's presence/relics |
This artistic approach is called aniconism—representing the Buddha through symbols rather than through a human image.
Sanchi is particularly valuable because its monuments preserve this early phase of Buddhist art. UNESCO describes the site as an important record of Buddhist aniconic art. (UNESCO World Heritage Centre)
Jataka Stories at Sanchi
The toranas are almost like an ancient stone picture book.
Among the most fascinating carvings are scenes from the Jataka tales, stories about the previous lives of the Buddha.
These stories communicate Buddhist values such as:
generosity
compassion
self-sacrifice
wisdom
kindness
moral conduct
Instead of simply writing philosophical teachings, the sculptors transformed them into visual stories that ordinary visitors could understand.
This makes Sanchi extremely important for understanding not only Buddhist religion but also ancient Indian society, clothing, architecture, animals, transport and everyday life.
The Ashoka Pillar at Sanchi
Near the Great Stupa are remains of an Ashokan pillar.
Like other pillars associated with Ashoka, it was made from finely polished sandstone and reflects the extraordinary stone-working technology of the Mauryan period.
The Ashokan pillar tradition is particularly important because Ashoka used pillars and inscriptions to communicate his ideas concerning Dhamma, morality and governance.
Sanchi's pillar therefore provides a direct connection between the monument and the Mauryan imperial world of the 3rd century BCE. (UNESCO World Heritage Centre)
Sanchi Stupa No. 3
Sanchi is not just one stupa.
The archaeological complex contains several stupas, with Stupa No. 1 (Great Stupa) being the largest and most famous.
Stupa No. 3 is particularly significant because it contained relics associated with two of Buddha's principal disciples:
Sariputra
Maudgalyayana
Their relics are of enormous importance in Buddhist tradition and continue to be revered. UNESCO specifically notes that their remains at Sanchi have been venerated by Theravada Buddhists and remain objects of devotion. (UNESCO World Heritage Centre)
Why is Sanchi important in Buddhism?
Sanchi has several layers of Buddhist significance.
1. An early Buddhist sacred centre
Sanchi became an important Buddhist centre beginning in the Mauryan period.
2. Association with Ashoka
Its foundation is connected with Emperor Ashoka, one of the most influential patrons of Buddhism in ancient history.
3. Relics
The stupas preserve or historically preserved sacred relics associated with important Buddhist figures.
4. Pilgrimage
The stupa became a place where devotees could honour the Buddha and Buddhist saints through ritual circumambulation.
5. Buddhist art
The carvings provide an extraordinary record of early Buddhist artistic traditions.
6. Buddhist teaching through sculpture
The Jataka stories and symbolic representations communicated Buddhist ideas visually.
7. Connection with the spread of Buddhism
Sanchi's historical environment is associated with the wider Mauryan effort that helped Buddhism spread across India and beyond. UNESCO identifies Sanchi as a major centre in the history of Buddhism. (UNESCO World Heritage Centre)
Sanchi and the Spread of Buddhism to Sri Lanka
Sanchi also has an important connection with Sri Lankan Buddhism.
Buddhist traditions associate Ashoka's son Mahinda with the Buddhist mission to Sri Lanka. UNESCO notes that Sanchi is identified with the ancient sacred site of Cetiyagiri in Sri Lankan Buddhist chronicles and connects the site with Mahinda's journey. (UNESCO World Heritage Centre)
This gives Sanchi significance beyond India: it forms part of the larger story of how Buddhism travelled from the Indian subcontinent to other parts of Asia.
Sanchi as a UNESCO World Heritage Site
The Buddhist Monuments at Sanchi were inscribed on the UNESCO World Heritage List in 1989.
UNESCO considers Sanchi outstanding because the site preserves an extraordinary combination of:
stupas
temples
monasteries
pillars
sculptures
inscriptions
Buddhist architecture
early Buddhist art
The monuments collectively document the development of Buddhism from the 3rd century BCE to the 12th century CE. (UNESCO World Heritage Centre)
Sanchi: More Than a Monument
One of the biggest mistakes is to think of Sanchi simply as "Ashoka's Stupa."
The reality is much more interesting.
Sanchi is a living historical record of several centuries.
Ashoka established the original sacred centre. The Shungas transformed and enlarged the stupa. Later rulers and donors added architectural and artistic elements. The Satavahana period produced the magnificent gateways, while the Gupta period contributed further shrines and structures.
In other words, Sanchi is a monument built across generations.
Its importance comes precisely from this continuity.
What makes Sanchi unique?
Sanchi is special because you can stand in one place and see several chapters of Indian history together:
Mauryan Empire → Shunga period → Satavahanas → Kushanas/Kshatrapas → Gupta period → Early Medieval Buddhism
UNESCO describes the site as one of the oldest Buddhist sanctuaries and notes that it remained an important Buddhist centre until the medieval period.
Sanchi for a Traveller
For anyone interested in Indian history, Buddhism, architecture, archaeology or ancient art, Sanchi is one of the most rewarding heritage sites in India.
It is located in Madhya Pradesh, close to Vidisha and about 46 km northeast of Bhopal.
A visit should ideally include:
Great Stupa – Stupa No. 1
All four toranas
Ashokan Pillar
Stupa No. 2
Stupa No. 3
Ancient monasteries
Gupta-period temples
Sanchi Archaeological Museum
A good way to understand the site
Don't simply walk around the Great Stupa and take photographs.
Walk clockwise around the stupa and study the toranas slowly.
Look for the Buddha represented through symbols, identify the Jataka stories, observe the animals and examine how ancient Indian sculptors represented people, buildings, clothing and royal processions.
That transforms a visit to Sanchi from ordinary sightseeing into a journey through 2,000+ years of Buddhist history and Indian art.
Conclusion
The Great Stupa of Sanchi is one of India's greatest surviving monuments of ancient Buddhism.
Its story began in the 3rd century BCE under Emperor Ashoka, but the monument we see today is the result of additions and transformations made by successive generations.
Its enormous dome represents the ancient Buddhist stupa tradition; its four magnificent toranas preserve some of the finest examples of early Indian sculpture; its Ashokan pillar connects the site with the Mauryan Empire; and the relics associated with Sariputra and Maudgalyayana give Sanchi profound religious significance.
Above all, Sanchi demonstrates how architecture, sculpture, religion and storytelling came together in ancient India.
For a visitor interested in the history of Buddhism, Sanchi is not simply a monument to photograph—it is a place where the early history of Indian Buddhism can still be read in stone.
