XÂM DƯƠNG COMMUNAL HOUSE

Xâm Dương Communal House is located in Xâm Dương village, Hồng Vân commune, Hà Nội city; it previously belonged to Ninh Sở commune, Thường Tín district, Hà Nội city. Xâm Dương is an area near the Red River, with a long history of settlement and one of the culturally and religiously rich areas of Thường Tín. Within the relic system of the region, Xâm Dương Communal House has a distinct position from Đền Dầm (Xâm Dương Linh Từ), which is located in the same village area. Existing documents also record that Xâm Dương Communal House is a relic that has been invested in for restoration and embellishment; the project to restore and embellish the Xâm Dương Communal House relic was approved by the People's Committee of Thường Tín district in 2025 and continued to be adjusted in the contractor selection plan in 2026.

According to documents on the deity's legend, the tutelary deity worshiped at Xâm Dương Communal House is a martial deity from the Hùng Vương era, with the honorific title Kiến Quốc Hùng Cơ. Legend has it that he helped Sơn Tinh defeat the Thục army and protect the country under the eighteenth Hùng Vương. The legend also links this deity with a system of water-palace deities, including children born from an egg sac; the first child was called Nhất Vĩnh Đông Hải, and the last child was Tứ Vĩnh Ninh Giang. These details show that the tutelary deity belief of Xâm Dương has a fairly clear connection with the belief system of water deities in the Red River Delta.

The worship of a deity originating from the Hùng Vương era also gives Xâm Dương Communal House a special layer of cultural value. The tutelary deity is not only revered by the community as the village's protective deity but is also regarded as a deity with merit in protecting the country and the people. This belief reflects the traditional conception of agricultural residents in the Northern Delta: the village has a tutelary deity to shelter and bless the villagers, and it is also a focal point for the community during sacrifices, village festivals, and traditional cultural activities.

In terms of architecture, the communal house bears the basic characteristics of the Northern village communal house space, a place combining the function of worshiping the tutelary deity and community activities. The communal house space includes the yard area, worship structures, and auxiliary items; traditional architecture is expressed through the tile roof system, wooden structure, truss sets, and the rear sanctuary space—where the deity's throne and tablet are placed. Over time, the relic has undergone repairs and restorations to meet conservation requirements and serve the local people's religious activities. The fact that the locality has implemented a separate restoration and embellishment project for Xâm Dương Communal House shows that the relic is still identified as a cultural and religious work that needs to be preserved and promoted.
