The event attracts tens of thousands of local people and visitors 

In 968, after putting down the anarchy of the 12 warlords, Dinh Bo Linh set up a heaven worship platform and declared himself king under the name Dinh Tien Hoang. He named the country Dai Co Viet (Great Viet) and set up the capital in Hoa Lu, which is now Ninh Binh 

The establishment of Dai Co Viet heralded a new era for the country after a millennium under the rule of dynasties from the north 

The re-enactment of Dinh Tien Hoang's coronation and the heaven worship ritual was one of the activities marking 1,050 years of the foundation of Dai Co Viet
