Trieu Dong Outer Communal House

Trieu Dong Outer Communal House in La Thanh Hamlet, Doai Phuong Commune, Hanoi City. It is located on beautiful terrain at the head of the village, facing southwest. The communal house has an architectural layout in the shape of the character “Nhat”, bearing strong imprints of the traditional architecture of Vietnamese village communal houses in the Northern Delta region.

The building Dai Bai was built in the style of three bays and two side wings, with a traditional wooden structure including upper beams, tie beams, purlins, and crossbeams; the trusses are made in the style of “rafters and braces with crossbeams concealed behind the main column row”. On the two tie beams are carved the characters “Phu – Quy – Tho – Khang – Ninh” and “Can – Nguyen – Hanh – Loi – Trinh”, expressing the villagers' aspirations for a peaceful, prosperous, and enduring life. Decorative motifs are concentrated mainly on the long thrones and memorial tablets, dating from the 18th century.

The communal house worships Three Tan Vien Son Thanh Deities and Tay Ky Vuong Nguyen Kinh. The Three Tan Vien Son Thanh Deities are the leading gods in the Four Immortals of Vietnamese folk belief, symbols of sacred power and the nation's enduring existence, worshipped by people in many regions, especially in the Tan Mountain – Da River area. Tay Ky Vuong Nguyen Kinh was a historical figure of great merit who was granted a title by the court in the early 16th century; after his death, he was honored by the people of Trieu Dong Village as the village's Tutelary God.

Trieu Dong Outer Communal House currently preserves many valuable historical and cultural artifacts, including: 4 sets of long thrones and memorial tablets from the 18th century; 2 genealogical records; 2 Tho Ha ceramic incense burners; 3 stone steles and 3 royal edicts, which are of great historical, cultural, and scientific value. Traditional festival of the village is held annually on the 6th day of the first lunar month.

With outstanding values in history, culture, and architecture, Trieu Dong Communal House has been the People's Committee of Ha Tay Province (former) classified Historical – Cultural Relic under Decision No. 1503/QD-UB dated December 29, 2004; it is now located in Hanoi City.
