Truong Yen Festival (also known as Hoa Lu Festival or Reed Flag Festival) is one of the oldest and most typical traditional festivals in Ninh Binh. The festival is held annually in Truong Yen Commune, Hoa Lu City, Ninh Binh Province – the central area of the ancient Hoa Lu Capital.
The festival takes place from the 8th to the 10th day of the 3rd lunar month every year, with some years starting as early as the 6th day of the 3rd lunar month. Notably, the scale of organization is expanded and especially significant during the main festival held every three years. The festival space is closely associated with the Hoa Lu Ancient Capital Special National Historical Monument complex, including key sites such as King Dinh Tien Hoang Temple, King Le Dai Hanh Temple, Nhat Tru Pagoda, Ba Chua Phat Kim Temple, Am Tien Cave, along with adjacent natural landscapes such as the Hoang Long and Sao Khe rivers, creating a unique cultural and historical ensemble.
