Trong Ngoc Kien Communal House

Ngoc Kien Communal House belongs to Ngoc Kien hamlet, Doai Phuong commune, Hanoi city, and is a typical cultural and religious community facility of the local population. The communal house worships the village tutelary god, the Three Tan Vien Mountain Saints, clearly reflecting the mountain deity worship associated with the lives of residents in the Northern Delta.

The relic is located in the center of the village, facing west-southwest. The current communal house complex includes a lotus pond, the Dai Bai hall, and the Hau Cung sanctuary. According to elderly residents, the communal house was previously built in the traditional Dinh-shaped architecture. However, during the resistance war against the French colonialists, because the area was heavily devastated by bombs and bullets, many ancient architectural items were damaged, leaving only some old carved panels.

The Dai Bai hall has three bays and two side wings, sloping roofs, closed gable walls, and simple truss structures, mainly prioritizing durability. Between the Dai Bai hall and the Hau Cung sanctuary is a small courtyard that acts as a skylight, helping to bring in natural light and create ventilation for the worship space. The Hau Cung sanctuary was built with three bays and two side rooms, roofed with di tiles, with a simple but solid architectural structure.

The Ngoc Kien Communal House festival is held annually from the 10th day of the second lunar month, an occasion for villagers to remember the merits of the tutelary god and maintain traditional cultural values. With its outstanding historical, cultural, and religious values, Ngoc Kien Communal House was ranked as a historical-cultural relic by the People's Committee of Ha Tay province under Decision No. 89-QD/UB dated January 28, 2004.
