Phú Nhi Communal House and Temple, Sơn Tây Ward, Hà Nội City

According to Sơn Tây local gazetteer documents and accounts from village elders, Phú Nhi Communal House was built long ago, with a grand architectural scale, and was once called by local people Đình Cả. The image of the communal house gate was recorded in photographs taken by the French from 1884 and printed on postcards. This is a valuable source of material reflecting the history and architectural appearance of the relic through different periods.

In terms of beliefs, Phú Nhi Communal House worships the three Tản Viên Sơn Thánh deities – the leading god in the Vietnamese belief of Tứ bất tử (Four Immortals), a symbol of the power to conquer nature and protect community life.
