Located in Chi Linh Town, the Con Son – Kiep Bac relic site played an important role in battles between the army of the Tran Dynasty (1226 - 1400) and the Yuan-Mongol invaders.
The site is closely associated with the life and career of Tran Quoc Tuan (or Tran Hung Dao), one of the most revered figures in Viet Nam’s history for his leading role in the country’s victory over Mongolian invaders in the 13th century.
It was also a central location in the pure and upright life of the Great Man of Culture of the World Nguyen Trai (1380-1442), one of Viet Nam's most famous poets and writers.
Con Son-Kiep Bac site was recognised as a national heritage site in 1962 and a special national heritage in 2012.
The Ministry of Culture, Sports and Tourism recognised Con Son-Kiep Bac spring and autumn festivals as national intangible cultural heritage in 2013.
The autumn festival traditionally takes place from the 15th to the 20th day of the eighth lunar month.
