1. Overview & Archaeological Significance
Kaveripattinam, immortalized in ancient Sangam literature as *Puhar* or *Kaveripoompattinam*, was the legendary royal maritime port and premier commercial metropolis of the Early Chola dynasty from approximately the 3rd century BCE to the 5th century CE. Situated at the historic estuarine confluence where the sacred Kaveri River empties into the Bay of Bengal in modern Mayiladuthurai district, Tamil Nadu, Puhar was celebrated in ancient Tamil epics—most famously the immortal *Silappadikaram* by Ilango Adigal and *Manimekalai* by Sithalai Sathanar—as a cosmopolitan global trade emporium where merchants from Rome, Greece (*Yavanas*), Sri Lanka, Malaya, and China gathered to trade horses, gems, spices, pearls, and fine silk.
Located in the Mayiladuthurai district of Tamil Nadu, Kaveripattinam Puhar Ancient Submerged Port is centrally protected by the Archaeological Survey of India (ASI) as an irreplaceable landmark of South Asian civilization. Recognized for its ancient estuarine brick port & wooden wharf post-holes, brick ring wells, buddhist vihara foundations & sangam coastal architecture, the site provides profound insights into the technological prowess, cosmological beliefs, and cultural aesthetics of its ancient builders.
2. Dynastic Origins, Royal Patrons & Chronology
Classical Sangam texts, such as the *Pattinappalai*, vividly describe the bustling city divided into two grand sectors: *Maruvurpakkam* (the bustling harbor quarter near the sea filled with foreign warehouses, sailor taverns, and customs houses) and *Pattinappakkam* (the royal citadel with wide avenues, king's palace, and philosopher gardens). According to literary tradition and geological findings, this glittering coastal capital was overwhelmed and largely submerged beneath the ocean by a catastrophic tsunami or marine transgression (*kadalkol*) in the late 5th or 6th century CE.
During the 1960s and 1970s, systematic archaeological excavations conducted by the Archaeological Survey of India (ASI) at Kilaiyur, Vanagiri, and Pallavanesvaram unearthed sensational material confirmation of the ancient port, including an ancient brick-built shipping wharf, wooden mooring posts, a Buddhist monastery (*vihara*), and Roman amphora jars. Today, Kaveripattinam stands as a profound pilgrimage destination connecting ancient Tamil literature, marine archaeology, and maritime history.
3. Structural Engineering & Architectural Design
The excavated archaeological remains at Kaveripattinam demonstrate advanced estuarine port engineering from the early historic Sangam era. At Kilaiyur, archaeologists uncovered a massive semi-circular shipping wharf constructed from large kiln-baked bricks measuring 42 x 21 x 7 cm, supported by sturdy wooden post-holes into which wooden mooring posts were driven to tie incoming ocean vessels.
At nearby Pallavanesvaram, excavations exposed the complete floor plan of a 4th-century CE Buddhist monastery (*vihara*), consisting of individual monks' cells, central meditation courtyards, and an ornate stucco-decorated Buddha shrine, confirming the cosmopolitan religious tolerance celebrated in the epic *Manimekalai*.
Additional archaeological structures unearthed across the coastal dunes include ceramic ring-wells, ancient water storage cisterns, brick-lined soak pits, and pottery kilns. Underwater archaeological expeditions conducted by the National Institute of Oceanography (NIO) identified submerged brick masonry structures, stone anchors, and pottery fragments extending up to 5 kilometres offshore at depths of 5 to 20 metres.
4. Archaeological Excavations, Epigraphy & Conservation
ASI excavations in 1962–1965 directed by K.V. Soundara Rajan uncovered the brick boat-wharf at Kilaiyur, Buddhist vihara at Pallavanesvaram, and a terracotta ring-well.
Underwater marine archaeological surveys by the NIO Goa and Tamil Nadu State Archaeology Department in the 1990s documented submerged man-made features and stone anchors off Poompuhar.
Recovered artifacts include square copper coins of the Early Cholas depicting an elephant on the obverse and a tiger on the reverse, alongside Roman rouletted pottery and beads.
The excavation sites and beach are freely accessible. The Silappathikara Art Gallery charges a nominal entry fee of ₹5 for adults and ₹2 for children.
