From the 3rd century B.C, An Duong Vuong established Au Lac Kingdom and selected Co Loa as the capital of the country. And more than 1000 years later, under Dai Viet Kingdom, Ngo Quyen – an excellent general who ended a millennia of Chinese occupation in 938, also chose Co Loa to establish the capital. This place preserves a series of archaeological relics reflecting the continuous development of the Vietnamese people from at the beginnings through historic periods. Therefore, through the discovery of Co Loa Citadel, archaeologists discovered a unique and valuable Dong Son culture, also known as the Red River civilization of the Vietnamese people in the prehistoric time.

Structure of the citadel

Co Loa Citadel was built in a spiral-shaped type. According to legend, the citadel had 9 walls, however, after the discovery, archaeologists found only 3 main walls left.

The Outer Wall (Thanh Ngoai): with a circumference of about 8 kilometers, and average height of 4-5 meters was built in the method of digging the soil while making moats.

The Middle Wall (Thanh Trung): with the same structure as the Outer Wall but had a narrower and more solid area with a circumference of about 6.5 kilometers.

The Central Wall (Thanh Noi): was the residence of the king and some mandarins, so it had a rather small circumference of about 1.65 kilometers. Later, An Duong Vuong Temple, Temple of My Chau Princess and a number of famous historical structures were built in this area.
