The citadel was built in 1397 by Ho Quy Ly, the then Prime Minister. Legend has it that the construction was completed after only three months. The citadel was a unique architectural project, with all of its walls and four main gates made of green square stone plates which were beautifully carved and overlapped tightly one after another. On the average, each stone plate is 1.5m long and 1m thick and some weight up to 15-20 tonnes. The shape of the citadel is fairly square, with its north and south sides being 870.5m long and its east-west sides being 883.5m long. Its four gates in the south, north, west and east were called the front, back, left and right gates and are domed. The stone plates on the dome were carved as sections of a grapefruit, tightly overlapping. The front gate in the south is the main gate and has three doors. The middle door is 5.82m wide and 5.75m high. The side doors are 5.45m wide and 5.35m high. Each of the remaining gates has only one door. The wall of the citadel is 5-6m high on average, with the highest peak being the front gate of 10m high. Scientists estimated that the entire walls were made of 25,000m3 of stones. Inside the stone walls is another wall made of approximately 80,000m3 of earth.

After the citadel was built, Ho Quy Ly forced King Tran Nhan Tong to move the capital to Thanh Hoa. In February of the Year of the Dragon (1400), after coming to the crown replacing Tran Thuan Tong, Ho Quy Ly renamed the country Dai Ngu (1400-1407).

According to historical books, in the citadel there were Hoang Nguyen, Dien Tho and Dong Cung Palaces, Tho Ky and Duc Tuong Mountains, Duc Thuy Lake ,… which were very magnificent and superb. Due to harsh weather and wars, many architectural works in the citadel were destroyed and only a part of the citadel’s walls and four gates remained.

The Ho Dynasty’s citadel is a cultural-historical relic which has been classified as a national relic by the Vietnamese State . It was the sole citadel built from stone and was connected with a dynasty which existed for a short period of time (1400-1407) but had remarkable innovations, such as reforming examination, building more schools, heightening the Nom scripts and issuing banknotes.
