Kim Ngân Communal House

Kim Ngân Communal House (formal name: Kim Ngân Đình Thị, also known as the Lower Communal House) is a đình (communal house) located at 42–44 Hàng Bạc Street, Hoàn Kiếm Ward, Hà Nội. The building was erected by the community of goldsmiths from Châu Khê village on Hàng Bạc Street and venerates Hiên Viên under the title Ancestor of a Hundred Crafts. The Ministry of Culture, Sports and Tourism classified the communal house as a national architectural and artistic monument under Decision No. 4065/QĐ-BVHTTDL dated 24 October 2012.

The people of Châu Khê once established two communal houses on Hàng Bạc: Kim Ngân Đình Thị, i.e. the Lower Communal House, at number 42, and Kim Ngân Trương Thị, i.e. the Upper Communal House, at number 50; the Upper Communal House no longer exists. Nguyễn Thị Thanh explains the name "Kim Ngân Đình Thị" as "Kim Ngân Market Communal House". According to her, this name reflects the dual function of the building: to worship the craft ancestors and to serve as a place for trading and exchanging goldsmith products. The archive of rubbings collected by the École française d’Extrême-Orient in the early 20th century contains three documents recording the name "Kim Ngân Market Communal House" belonging to Đông Thọ hamlet. The communal house was built during the Later Lê dynasty, but the exact date of its original construction is unknown. Hà Nội scholar Nguyễn Vinh Phúc believes the building dates from the late 15th or early 16th century.

During the reign of Lê Thánh Tông, the court assigned Lưu Xuân Tín, a native of Châu Khê and Minister of Personnel, to establish a silver ingot casting workshop in Thăng Long. He brought people from Châu Khê to Đông Các ward to practise the craft; from casting silver ingots, this community developed into making gold and silver jewellery. The silver casting workshop was located at what is now 58 Hàng Bạc. The two communal houses of the Châu Khê people served as places for meetings, rituals, receiving raw materials, and handing over silver ingots to court representatives.

Kim Ngân Communal House was expanded under the Gia Long reign. Initially, it was also used for exchanging silver ingots, passing on the craft, and worship. In the 19th century, when silver casting activities were moved to Huế, the communal house continued to serve as a place for currency exchange for a time. From 1890, the building mainly served meetings and rituals; during wartime periods, it was used for teaching the Quốc ngữ script, nurse training, and military drills.

After 1954, more than 20 households moved into the communal house; the worship space was reduced, the grounds were partitioned into small rooms, and many parts were extended or damaged. The ceremonial hall was once divided to make a library, while the households and agencies left only a narrow passage to the sanctuary. Before restoration, one entrance served as a police station, the other became a thoroughfare; within the grounds were residential spaces and encroaching structures.

In 2004–2005, the Hà Nội Old Quarter Management Board, together with Vietnamese and French experts, surveyed the current state, documentation, and architectural and religious values of the building. In 2009, the city decided to relocate 25 households with 83 residents from the communal house and assigned the Old Quarter Management Board to implement a restoration project with technical support from Toulouse experts. The project was completed in January 2011; the completion and reopening ceremony was held on 26 March 2011.

On 24 October 2012, the Ministry of Culture, Sports and Tourism issued a decision classifying Kim Ngân Communal House as a national architectural and artistic monument. The certificate awarding ceremony was held at the communal house on 29 March 2013.

The grounds of the communal house cover about 575 m². Due to its location in a densely built-up area, the building has a narrow frontage and extends deep, but still retains the layout of a village communal house. The nghi môn (ceremonial gate), courtyard, tiền tế (front ceremonial hall), and hậu cung (sanctuary) are arranged in the shape of the Chinese character Công (工). The main hall and sanctuary each have three bays; the sanctuary is elevated, with its own altar platform and partition. The main hall and sanctuary are connected by a two-roofed corridor; the lower roof creates open spaces on both sides.

The architectural decoration is in the style of the 18th and early 19th centuries. The central bay of the main hall has multiple layers of võng doors (carved wooden screens); the beam ends, trusses, and superimposed rafters are carved with motifs of dragons facing the sun, clouds, fretwork, plants, and the four sacred animals: dragon, kylin, tortoise, and phoenix. The communal house also preserves some ritual objects, including a system of võng doors, thrones, and incense tables.

The communal house venerates Hiên Viên under the title Ancestor of a Hundred Crafts. The communal house is renowned for the goldsmith trade, but Lưu Xuân Tín (whom the Châu Khê community honours as the ancestor of goldsmithing) is not worshipped here. In her dissertation on Hà Nội's urban architectural heritage, Đào Thị Như classifies the communal house on Hàng Bạc Street as a vọng shrine (place of distant worship) built by migrant craftsmen to maintain ties with their native Châu Khê. According to her, later this space also served groups of residents from other origins. Đỗ Đông Hưng relates the choice of Hiên Viên to the occupational composition of Hàng Bạc: besides people from Châu Khê, the street also had craftsmen from Định Công, Đồng Xâm, Đại Bái, and Kiêu Kỵ. He also notes that the goldsmiths' ancestor death anniversary on Hàng Bạc is held annually on the 22nd day of the 4th lunar month, and Châu Khê people still participate in rituals at the communal house.

After restoration, the communal house continues to serve religious activities, goldsmithing exchanges, and folk cultural events. In the 2010s, the Hà Nội Old Quarter Management Board used Kim Ngân Communal House as a venue for craft demonstrations and traditional music performances, especially during festivals and Tết. In 2019 and early 2020, the communal house was the regular venue for ca trù performances by the Hà Nội Ca trù Club. In December 2020, the National Archives Centre I, in collaboration with the Old Quarter Management Board, organised the exhibition "Hà Nội Old Quarter – Traces of Ancient Craft Villages" at the communal house. The exhibition used copies of archival documents to present the process from craft village to craft street and the worship of craft ancestors.

In a 2022 study, Nguyễn Thu Phượng observed that the management of the Kim Ngân festival at that time was mainly carried out by state agencies, without evident cooperation with the community.

The 2023 Kim Ngân Communal House festival and goldsmiths' guild festival included a procession, incense offering, craft demonstrations, and exchanges with artisans. The programme was supported by artisans and communities from Định Công, Châu Khê, Đồng Xâm, Đại Bái, Kiêu Kỵ, and Ngũ Xã, along with several cultural organisations in Hà Nội. Through observation at the festival, Đỗ Đông Hưng recorded that the Châu Khê delegation participated in the procession and was responsible for demonstrating the silver ingot casting process.

In 2025, the Hoàn Kiếm Lake and Hà Nội Old Quarter Management Board launched the project "Kim Ngân Communal House Storytelling Space". The project uses the communal house's decorative motifs and architectural spaces to organise exhibitions, craft demonstrations, and share knowledge about the crafts of the old quarter.
