Flowers were scattered at Nandikadal lagoon by Tamil activists including former Northern Provincial Council member Thurairasa Ravikaran to mark Tamil Genocide Remembrance Day.
This year marks 15 years since Sri Lanka's genocidal offensive that massacred tens of thousands of Tamils.
Ravikaran said that Nandikadal is "a silent witness of the sad final scenes of our glorious history and is filled with our tears and blood of our relatives."
