India’s oldest cities are not simply historic settlements. Many emerged during the earliest phases of organised civilisation in South Asia and survived through shifting empires, trade routes, invasions, and religious transformations. Some were thriving long before modern capitals like Tehran rose to prominence in Iran during the late 18th century.
Several of these Indian cities also developed connections with the Persian world through trade, art, administration, architecture, and language. Together, they reveal how ancient India was never isolated, but deeply linked to wider Asian civilisations stretching from the Gangetic plains to Persia.
Varanasi
Varanasi is often described as one of the world’s oldest continuously inhabited cities. References to the city appear in ancient Hindu scriptures, and historians believe it has existed for more than 3,000 years. Located on the banks of the Ganges, it emerged as a centre of learning, philosophy, and religion during the Vedic age.
The city became part of wider intellectual networks that connected India with Persian scholars and travellers centuries later. Though Tehran itself was still a relatively minor settlement in medieval times, the broader Iranian world already shared linguistic and cultural exchanges with northern India.
Patna
Ancient Pataliputra, now Patna, was among the greatest imperial capitals of the ancient world. It became the centre of the Mauryan Empire under Chandragupta Maurya and Ashoka during the 4th and 3rd centuries BCE.
Historians have often pointed to similarities between Mauryan imperial architecture and the earlier Achaemenid Persian Empire. Pillars, court layouts, and administrative methods may have been influenced by Persian traditions that spread eastward from ancient Iran.
Delhi
Delhi’s roots stretch far beyond the medieval era. Archaeological remains around Purana Qila are linked by some historians to ancient Indraprastha from the Mahabharata.
Over time, Delhi also became one of the most Persian-influenced cities in South Asia. Persian served as the language of governance and elite culture for centuries. Long before modern Tehran became Iran’s capital, Delhi had already evolved into a major Indo-Persian political and literary centre.
Ujjain
Ancient Ujjain, known as Avanti, was one of the great cities of the Mahajanapada era. It functioned as a centre of trade, astronomy, and governance centuries before the Common Era.
Because it sat along important commercial routes, Ujjain connected indirectly to trade systems extending toward Persia and Central Asia. Ancient Indian merchants moved goods westward through routes that eventually linked with the Iranian plateau.
Madurai
Madurai represents the sophistication of the Sangam era, the classical age of ancient Tamil civilisation. The city flourished more than 2,000 years ago as a centre of literature and political power.
South India’s maritime trade routes connected Tamil kingdoms with the Persian Gulf long before modern nation-states existed. Traders from regions associated with ancient Persia regularly sailed across the Indian Ocean to ports in peninsular India.
Kanchipuram
Kanchipuram emerged as a major centre of religion, education, and temple architecture under the Pallavas. Its origins predate the medieval period, and it became known across Asia for scholarship and philosophy.
The city reflected the urban sophistication of early South Indian civilisation at a time when trade and cultural exchange connected India with both Southeast Asia and western Asia.
Mathura
Mathura became a major urban centre by at least the 6th century BCE. During the Kushan period, it developed into one of the subcontinent’s most important artistic hubs.
The Kushans themselves ruled territories stretching into regions shaped by Iranian and Central Asian cultures. This gave Mathura a cosmopolitan atmosphere shaped by multiple civilisational influences.
Ayodhya
Ayodhya occupies a central place in ancient Indian epic traditions and developed into an important urban settlement during the early historic period.
Excavations suggest continuous habitation dating back many centuries before the Common Era. The city reflects the growth of organised kingdoms across the Gangetic plains during ancient India’s formative urban age.
Dwarka
Dwarka stands at the intersection of mythology, archaeology, and maritime history. Marine excavations near the Gujarat coast have revealed submerged structures believed by some researchers to be linked to ancient settlement activity.
Gujarat’s coastline maintained trade links with Persia for centuries. Merchants moved between western India and ports connected to the Iranian world across the Arabian Sea.
Rajgir
Before Pataliputra became dominant, Rajgir served as the capital of Magadha. The city was protected by massive stone fortifications known today as cyclopean walls.
Rajgir played a major role in the early development of Buddhism and Jainism, making it one of the most historically layered cities in ancient India.
Amaravati
Ancient Amaravati flourished under the Satavahanas and became a major Buddhist centre from around the 3rd century BCE onward.
Its sculptural traditions reveal a cosmopolitan culture shaped by trade networks extending across the Indian Ocean world.
Puri
Puri developed into one of eastern India’s major sacred cities. Although the present Jagannath Temple belongs to the medieval period, the city’s ritual significance is far older.
Its coastal position also connected it to maritime trade systems stretching beyond India.
Thanjavur
Thanjavur rose under the Cholas, whose naval power transformed South India into a major maritime civilisation.
The fertile Kaveri delta had supported organised settlement long before the Chola period, making the region one of the oldest continuously cultivated zones in India.
Vijayawada
Situated along the Krishna river, Vijayawada contains evidence of early habitation, cave architecture, and religious activity from the early historic era.
Its strategic location connected northern and southern India through inland trade routes.
These cities demonstrate that India’s ancient urban story was part of a much larger Asian civilisational network. Long before Tehran emerged as the capital of Iran in the late 1700s, older Persian empires had already exchanged ideas, trade, artistic styles, and political systems with the Indian subcontinent.
