Colonial records describe massive temple structures pushed into the sea. Underwater surveys found carved granite blocks suggesting the temple complex was far larger than surviving ruins indicate.

A Temple Toppled
The Koneswaram Temple, also called the Temple of a Thousand Pillars, originally was a massive black granite complex on the highest point of Swami Rock. Its gopuram towers were visible to sailors far out in the Indian Ocean. Historical accounts describe it as one of the most important Hindu pilgrimage sites in the world, with a history possibly dating back to before 400 B.C. The complex was expanded by various southern Indian dynasties, including the Pallava, Chola, and Pandyan empires.
This ended abruptly in the 17th century. On Tamil New Year's Day, April 14, 1622, Portuguese soldiers under the command of Constantino de Sá de Noronha attacked the temple. Over the next two years, the entire complex was systematically demolished. The Portuguese used the granite blocks from the sacred structure to construct Fort Frederick, which still is on the promontory today. What they did not repurpose, they simply pushed over the cliff edge into the sea. The destruction was so complete that the temple's full scale was lost to memory for over 300 years.
Rediscovery Beneath the Waves
In 1956, science fiction author Arthur C. Clarke and photographer Mike Wilson were scuba diving at the base of Swami Rock. In the shallow water, they found evidence of the lost temple. Scattered across the seabed were huge, carved stone blocks, capitals from doorways, and broken pillars bearing lotus-petal designs. The underwater ruins included stones carved to look like elephant heads and masonry with clear Tamil, Pallava, and Chola architectural styles from the 3rd to 9th centuries.
Subsequent dives and archaeological work confirmed the site's identity. Divers located and retrieved many artifacts, including a sacred stone obelisk known as the Swayambhu lingam. In 1950, while digging a well about 500 yards from the temple site, workers had also uncovered a cache of 10th-century bronze statues of Hindu deities, likely buried by priests during the 1622 attack. These underwater and buried discoveries showed that the historical accounts of a grand "Thousand Pillar" temple were accurate. The recovered artifacts were incorporated into a new Koneswaram temple, which was completed and consecrated on the original site in 1963.
💡Fun Facts
Science fiction author Arthur C. Clarke was one of the first people in the modern era to dive on and publicize the existence of the temple's underwater ruins.
The Portuguese commander who ordered the temple’s destruction, Constantino de Sá de Noronha, had drawings made of the original structure, ironically preserving a record of what he was about to demolish.
Divers discovered that the cliffs of Swami Rock continue underwater as a vertical wall, plunging to a depth of 24 meters.
Some of the recovered 10th-century bronze statues are considered masterpieces of Chola-era sculpture.
The temple is generally open from 6:00 AM to 1:00 PM and 4:00 PM to 7:00 PM. Pooja (prayer) ceremonies often occur at 6:00 AM, 8:00 AM, and 11:00 AM.
Admission
Free.
Accessibility
The temple is located within Fort Frederick on a high promontory. Reaching it requires walking up a road past an active military base. The terrain around the temple itself can be uneven.
