Constructed on the remains of a 7th century Chinese fortress, the Thăng Long Imperial Citadel was built on strategic reclaimed river lands on the lower Red River Delta and for nearly 13 centuries, remained the regional powerhouse of Northern Vietnamese political & military domination. Shortly after his ascension to the throne, Emperor Lý Thái Tổ declared a royal decree in the year 1010, to move the capital from Hoa Lư and establish a new Imperial City for the Lý Dynasty.

Located south of the Red River Delta Region 90 km's from Hanoi, Hoa Lư was a bustling capital city in turmoil during the 10th and 11th centuries. For a short time, it was the economic, political and cultural centre of medieval Vietnam. In 968 A.D, it was strategically built in a flat verdant valley, protected between steep limestone mountains, which created a virtually impenetrable barrier to human traffic.
