An Duong Vuong, succeeding the era of the nation founders Hung Kings, is credited with establishing Au Lac, an ancient state in Viet Nam.

His strategic vision and unwavering determination in national construction and defence led him to relocate the nation's centre from the northern mountainous region to the vast and fertile plains where he established the ancient capital, known today as Co Loa.

Through extraordinary efforts, An Duong Vuong and the people of Au Lac completed the construction of the Co Loa Citadel, featuring a unique spiral three-tiered architectural design, within a remarkably short period./.
