Thượng Cát Communal House

Thượng Cát Communal House dates from the 17th century (1633) during the Lê Trung Hưng period; the relic is named after the former Thượng Cát village. Previously, the relic was also called “Từ Thượng Đẳng” temple. Thượng Cát Communal House worships the village tutelary deity Quách Lãng Tướng Công and the two princesses Đinh Bạch Nương and Đinh Tĩnh Nương.

Thượng Cát village communal house was built in the “inner Công, outer Quốc” style. The three-entrance gate consists of four brick pillars forming three gates with wooden doors, topped with small roofs and slightly curved đầu đao. The communal house courtyard is shaded by four ancient muỗm trees, with two rows of left and right wings on either side. The main hall has seven bays and two roofs; the veranda is carved in relief with dragons, phoenixes, white snakes, and wooden patterns. Before the communal house threshold steps is a pair of stone dragons with rough carving. On the roof is a pair of relief dragons facing the sun; four curved roofs feature four pairs of dragons and four pairs of nghê in relief beside the four curved roofs. The rear sanctuary is simple with enclosing boards. Inside are dragon thrones and tablets of the tutelary deities. In front of the main hall is a square pavilion, where ceremonies are held. The communal house still preserves many precious relics, including 33 royal edicts recognized by the Hanoi People's Committee as rare archival documents in 2021, along with horizontal plaques and couplets.

Every year, on the 10th day of the third lunar month, the villagers of Kẻ (Thượng Cát) hold a large festival to commemorate the merits of the deities and reenact the troop training and fighting of the three talented generals. The festival is also an occasion to strengthen community bonds, enhance the spirit of mutual affection and solidarity, and join in the common spirit of the village. At the festival, many folk games are revived and many cultural and sports activities are organized, especially the swimming contest at the communal house lake, which brings a distinctive feature to the local people and visitors when they come to the Thượng Cát communal house festival.

During the August Revolution, Thượng Cát Communal House was where a rally of more than 1,000 people took place, led by comrade Hoàng Tùng, who led the struggle and declared the abolition of the French colonial and feudal puppet administration, establishing a people's democratic government. During the resistance war against the American imperialists (1964–1972), Thượng Cát Communal House was used as a storage depot for military equipment and supplies by Unit K10 of the Logistics Department, Air Defense - Air Force Service.

With its outstanding values, Thượng Cát Communal House was ranked as a national historical-cultural relic by the Ministry of Culture - Information (now the Ministry of Culture, Sports and Tourism) under Decision No. 490/QĐ-BT dated April 22, 1992.
