Batticaloa
'Batticaloa' is a name that comes from the portuguese language. Batticaloa has a nickname -  "Land of the singing fish" (Tamil: மீன் பாடும் தேன் நாடு) due to musical sounds that related to fish or aquatic creatures in the Batticaloa Lagoon near the Kallady Bridge. BBC Radio 4 was able to record the mysterious sound in Batticaloa Lagoon. The sound was broadcast by Sri Lanka Broadcasting Corporation in 1960s with the help of Rev. Fr. Lang, a Catholic priest.
