Turkish President Recep Tayyip Erdogan has given emotional speeches to tens of thousands of people a year after a coup attempt was faced down in the streets.
Mr Erdogan said: "People that night did not have guns, they had a flag and more importantly, they had their faith."
He backed the death penalty for coup plotters and said they should wear Guantanamo Bay-style uniforms.
Nearly 250 people died and 2,196 were wounded fighting the coup attempt by an army faction on 15 July last year.
The coup failed for several reasons, including a lack of support in higher echelons of the armed forces and a lack of political or public backing.
Mr Erdogan said that 250 people had lost their lives but the country had won its future.
He said he would "break the heads of the traitors" who plotted the coup.
Mr Erdogan also said he had spoken to Prime Minister Binali Yildirim about the coup plotters, saying: "When they appear in court, let's make them appear in uniform suits like in Guantanamo."
The president then unveiled a "martyrs' memorial" at the bridge, which has been renamed the Bridge of the Martyrs of July 15.
The date of 15 July has been declared an annual holiday called Democracy and National Unity Day..
