Chunar
The 1st-century BCE Chunar sandstone bluff and fort at Chunar in Mirzapur district, Uttar Pradesh, 40 kilometres from Varanasi — the quarry that supplied the famous 'Chunar sandstone' used for Ashoka's polished pillars across North India (c.258-243 BCE). The Chunar sandstone's unique chemical composition (high silica content with low iron oxide) produces the glass-like 'Mauryan polish' when sanded with fine abrasive. The Chunar bluff on the Ganga was quarried by Mauryan state engineers who transported the 10-15 ton pillar monoliths downstream by Ganga boat and then overland to the final sites (Lauriya Nandangarh, Rampurva, Topra, Sarnath and others). The 1st-century BCE Chunar Fort on the bluff was Vikramaditya's base (legendary), later held by Sher Shah Suri (1540), the Mughals (1545), the Awadh Nawabs (18-century) and the British (1764). ASI protection since 1917. The quarry remains in commercial sandstone operation.

Chunar is one important traditional source of Ashokan pillar stone, but provenance should not be treated as uniform for every pillar; Mathura sandstone is also attested.

- Ashokan stone from ChunarLauriyā Nandangarh pillar
The Lauriya Nandangarh pillar still stands where it was raised, with its lion capital, beside a large stupa mound in the Bihar terai — one of very few in situ. Its polished sandstone is traditionally traced to the Chunar quarries on the Ganga near Varanasi, several hundred kilometres away, which means monoliths of thirty and forty tonnes were cut, dressed, polished and moved upriver as a matter of routine imperial supply.
- Ashokan stone from ChunarRāmpurvā pillars
The two Rampurva pillars, one with a lion capital and one with a bull, stood on the old road from Pataliputra toward Lumbini and the Nepal terai — the route a pilgrim to the Buddha's birthplace would take. Their stone is traced to Chunar, as is most Ashokan pillar sandstone, so the empire's commemorative programme rested on a single quarry and a long river haul.
- Ashokan stone from ChunarFīroz Shāh Kotla & the Topra pillar
The Topra pillar that Firuz Shah moved to Delhi is Chunar sandstone, quarried on the Ganga near Varanasi and originally hauled to the Haryana plain — and then moved again, seventeen hundred years later, by a sultan with a fleet of barges. The same monolith has therefore been transported twice by two empires that had nothing in common except the wish to be associated with it.
- Ashokan stone from ChunarKaushāmbī pillar (now Allahabad Fort)
The Kaushambi pillar, later moved to Allahabad Fort and inscribed again by Samudragupta and Jahangir, is Chunar stone like the rest. The quarry is the hidden infrastructure behind the whole pillar programme: a single sandstone source, a river for moving forty-tonne shafts, and a workforce capable of the high polish that has kept these surfaces bright for two thousand three hundred years.
- Craft tradition ofSārnāth
The Chunar quarries on the Ganges supplied the stone for the Ashokan pillars, including the Sarnath lion capital, and the shafts were floated hundreds of kilometres downriver and then hauled overland. The Mauryan mirror polish achieved on that sandstone has never been satisfactorily explained and was not reproduced afterwards. The same quarries later supplied Mughal and then colonial building, so one riverside cliff face runs through the whole sequence.
