Overview
The Kallady Bridge crosses the Batticaloa Lagoon at its narrowest point south of the town, providing the primary road connection between the Batticaloa island and the eastern mainland coastal areas. The bridge is famous throughout Sri Lanka as the best listening position for the legendary “Singing Fish” of Batticaloa — on calm Poya (full moon) nights between April and September, a remarkable sound described as music, humming, or the sustained note of a cello rises from below the bridge in the lagoon depths. The acoustic phenomenon has been documented by scientists and travellers since the 19th century, and while the precise source (attributed variously to a species of mollusk, a fish, or a natural acoustic effect of the water) remains debated, the experience of hearing it on a still Poya night is genuinely extraordinary. The bridge also provides a pleasant elevated view over the lagoon.
