This village communal house was built out of bamboo on the hillock of Tam Vi in the early 19th century. In 1852, it was moved to the center of the village and was rebuilt using brick and pantiles. It has three sections and two lean-tos with a length of 14.5m and a width of 9.7m. There are 36 pillars made of jack tree and ‘kien kien’ wood. The structure is “Chong ruong - Gia thu” with the tops of the pillars carved with a dragon’s head and the beams with apricots, poplars, bamboo like phyllotaxis and orchids. There are also animals and birds such as sparrows and monkeys and ornamental floral designs. These original and artistic works are skillful and ingenuously carved.

In August 1945, before the usurpation of power, the local people gathered at the house to demonstrate and forced the court mandarin and village officials to hand over the seals, documents and record books. Bo Ban was the first local polling booth for the national congress election of the Democratic Republic of Viet Nam. In the anti - American resistance war, it was the place where the local people decided to wipe out the enemy mercenary killers, to destroy the confinement section and confiscate the arms and storehouses in Hoa Vang District.
