An ecumenical service was held at the stadium , attended by President Jose Eduardo dos Santos, government officials, politicians and church leaders.
At 1200 local time (1100 GMT) on Friday , a minute's silence was observed in honour of the victims of the civil war.
An estimated 500,000 people were killed and tens of thousands more were displaced during the 27-year civil conflict.
"This is a great day, now we have peace. We have struggled for a long time for this, and now, thanks to the Lord, we have peace. Angola has changed, it's changed a lot", a woman named Hortense said.

A 23-year-old man called Bartolomeu
told the BBC: "Angola has not changed. This peace has not led to better living conditions. Our president needs to rebuilt Angola. Angola has been destroyed".
