It was the first time the 1962 decision to award Preah Vihear temple to Cambodia has been marked and comes after bitter renewed wrangling between the two nations as Cambodia attempts to have the temple recognized as a World Heritage site.
Cambodia has rejected requests by Thailand to jointly manage the site and Thailand in turn has disputed border territory around the temple.
The head of the organising committee for the rally, Moeung Son, made a speech praising the International Court's decision.
"Thanks to the International Court for its verdict which gave Preah Vihear temple back to the Khmer people," he said.
No dignitaries attended the rally, but it had received the support of King Norodom Sihamoni in a letter last week.//dpa
