How Ancient Indian Temples Were Built Without Modern Machinery

Ancient Indian temples were built without modern machinery by combining careful planning, enormous skilled labour and simple but powerful tools: iron chisels, wedges, levers, rollers, ropes, earthen ramps and animal power. Master builders called sthapatis followed proportional systems from the Shilpa Shastras, and stones were often locked together with precise joints instead of mortar.

Stand beneath the 66-metre granite vimana of the Brihadeeswara temple in Thanjavur, or inside the Kailasa temple at Ellora, carved downward from a single hillside, and it is natural to wonder how people did this a thousand years ago. Social media sometimes answers with talk of lost technologies or outside help. The real answer is less mysterious and more impressive: generations of knowledge, organisation and human skill.

Who designed and built the temples?

Temple building in India was a specialised, often hereditary profession. At the top was the sthapati, the chief architect, who held responsibility for the design, proportions and ritual correctness of the building. Under him worked the sutragrahin (the surveyor who laid out lines with cords), the takshaka (stone carvers) and the vardhaki (who fitted and assembled). Around them were large teams of quarrymen, labourers, carpenters, blacksmiths who kept tools sharp, and people managing food and supplies.

Inscriptions confirm this. At Brihadeeswara, the Chola king Rajaraja I recorded the name of the chief architect, often read as Kunjara Mallan Raja Raja Perunthachan, along with lists of donors and temple staff. Families of traditional sthapatis still practise in Tamil Nadu today, and the government college of architecture and sculpture at Mamallapuram teaches the same principles.

What guided their designs?

Builders followed traditional manuals called Shilpa Shastras and Vastu Shastras, along with ritual texts called Agamas. Texts such as the Mayamata and Manasara describe site selection, soil testing, ground plans, proportions, the heights of storeys, the forms of deities and the ceremonies at each stage.

• Grid planning: many temples are laid out on a square grid called the vastu purusha mandala, with the sanctum at the centre.
• Modular proportions: dimensions were based on a unit, often derived from the width of the sanctum or the size of the deity, so every part related to every other.
• Orientation: most temples face east, toward sunrise, set out using the sun’s shadow on a gnomon.

This modular system meant that a large team could work on different parts at once and still produce a harmonious whole.

How was stone quarried?

Granite, sandstone, basalt and soapstone were the main materials, depending on the region. To split rock, workers cut a line of small holes or slots along a natural grain. Into these they hammered wedges, traditionally of wood or iron. Wooden wedges could be soaked with water so they swelled and split the stone. Iron wedges were struck in sequence until the block cracked along the line. You can still see rows of these wedge marks on rocks at Hampi and Mamallapuram.

Wherever possible, temples were built close to quarries, or, in the case of rock-cut temples, out of the quarry itself.

How were huge stones moved and lifted?

This is the question most people ask. The tools were simple, but used at scale:

A popular tradition about Brihadeeswara says that its capstone, estimated at around 80 tonnes, was dragged up a ramp several kilometres long, starting from a village called Sarapallam. Historians treat the exact length as tradition, but a long earthen ramp is consistent with how such stones could be raised, and similar methods are documented elsewhere in the ancient world. Some scholars have also suggested the capstone may be made of several pieces; this remains debated.

How did stones stay together without cement?

Many South Indian stone temples were built largely without mortar. Instead, builders used:

• Precise dressing: faces of blocks were ground so flat that they sat tightly together under their own weight.
• Interlocking joints: techniques borrowed from carpentry, such as mortise-and-tenon and tongue-and-groove, locked stones in place.
• Corbelling: each course projected slightly beyond the one below, allowing towers to rise and taper without true arches.
• Iron clamps and dowels: in some temples, like Konark, iron beams and clamps reinforced the structure.
• Gravity and mass: the sheer weight of the stone above held lower courses in compression, making the structure stable.

These methods also gave a degree of flexibility, which may help explain why some temples have survived earthquakes.

What about rock-cut temples like Kailasa?

Rock-cut temples reversed the usual process. Instead of building upward, workers carved downward and inward. At Ellora’s Kailasa temple, made mostly in the eighth century under the Rashtrakuta king Krishna I, builders first cut deep trenches into the basalt hillside to isolate a huge block, then carved the temple from the top down, leaving halls, pillars, bridges and sculptures in place. There was no room for error: a mistake could not be fixed by replacing a stone. It shows extraordinary planning and an exact mental model of the finished building before the first cut.

How long did it take, and who paid?

Timelines varied enormously. Brihadeeswara was built in roughly seven years, from about 1003 to 1010 CE, which tells us the Chola state could mobilise labour, materials and funds on a vast scale. Other temples grew over centuries, as successive rulers added walls, halls and gateways. Funding came from kings, queens, ministers, merchant guilds and villages, recorded in inscriptions that also list land grants made to sustain temple staff.

Is there any evidence of lost technology?

No credible archaeological evidence supports claims of lost machines or outside help. What the evidence shows is skilled human work: tool marks on stones, unfinished sculptures at sites like Mamallapuram that reveal carving stages, inscriptions naming architects and donors, and living craft traditions. The marvel is not that it seems impossible, but that people achieved it with skill, organisation and time.

Her View: Behind every temple are thousands of unnamed hands: the women who cooked for workers, the men who hauled stone, the carvers who spent years on a single pillar. They deserve to be remembered.

His Insight: Temple building was project management on a royal scale: design standards, supply chains, labour and finance. The Cholas would have understood modern infrastructure.

Frequently asked questions

How were stones lifted to the top of temples?

Using earthen ramps, levers, rollers, ropes, simple pulleys and animal power, raising blocks gradually as the structure rose.

Did ancient Indian temples use cement?

Many stone temples were built largely without mortar, using precisely cut interlocking joints and the weight of the stone. Lime mortar was used in brick and stucco work.

Who was the sthapati?

The chief architect responsible for design, proportions and ritual correctness, leading teams of surveyors, carvers and builders.

How long did it take to build Brihadeeswara?

About seven years, from around 1003 to 1010 CE.
