According to the elders, Trung Kien communal house, located in Loc Tien commune, Phu Loc district, was initially built small, close to the foot of the mountain, near Dieu Ngo Pagoda, along the road to Bo Ghe Waterfall. The communal house was rebuilt in the early 19th century, along National Highway 1A, in front of the present-day People's Committee of Loc Tien commune, with a structure of 5 compartments and 2 wings, with tiled roofs.
In the year of Đinh Suu (1937), Mrs. Duong Thi Phu (Duong Thi An), the grandmother of King Bao Dai and the wife of King Dong Khanh (1885 - 1889), who was a descendant of the Duong family in Trung Kien village, provided financial assistance for the reconstruction of Trung Kien communal house and donated a large self-portrait painting inlaid with gold. On the left side, it is inscribed "In the year of Bao Dai, Đinh Suu, the sun shines brightly", in the middle are the large characters "Trung Kien Communal House", and on the right side is written "Duong Thi An, the virtuous Queen Mother of Thai Hoang Emperor, established this."
In 1945, comrades Tran Chi Cuong and Nguyen Dinh San gathered revolutionary forces at Trung Kien communal house, preparing weapons to overthrow the authorities. The communal house was then used as a venue for organizing activities and revolutionary training. On January 6, 1946, during the first election of the National Assembly after liberation, people gathered at Trung Kien communal house to cast their first ballots, with drums, flags, banners, and slogans.
In 1958 - 1959, following the division of the country into two regions, Trung Kien communal house came under the control of the Ngo Dinh Diem regime. They implemented Law 10/59 and used Trung Kien communal house as a place to detain and torture hundreds of revolutionary families across the district. Here, they subjected people to brutal torture reminiscent of the Middle Ages, including tying hands and feet and hanging them upside down on communal house beams, torture with chili, soap, electricity, acid, and more.
During the Lunar New Year of Mau Than in 1968, our troops attacked Trung Kien communal house, eliminating hundreds of enemy forces and restoring the tranquility it once had, which continues to this day.
