Argentina's President, Nestor Kirchner, has led a ceremony to mark the 30th anniversary of the coup that brought the military to power for seven years.
He unveiled a plaque with the words "Never Again" at the Military College.
Mr Kirchner also called on the judiciary to decide what action to take over the remaining immunity laws for Argentina's former military leaders.
Big crowds have gathered in Buenos Aires for a march to mourn the tens of thousands of victims of the coup.
At least 30,000 people were killed in what was known as the Dirty War. Many of the bodies have never been recovered.
