Cư thạch Tomb - or the ancient Hàng Gòn Tomb, as commonly called by locals - is a specially-ranked national archaeological heritage site located in Hàng Gòn commune, Đồng Nai province. Cư thạch Tomb lies on Highway 56, approximately 1 km away from the Phan Thiết - Dầu Giây expressway.
Hàng Gòn Cư thạch Tomb is one of the unique and rare archaeological sites in Vietnam, Southeast Asia, and the world, belonging to a type of burial site dating back approximately 2000-2500 years.
Hàng Gòn Cư thạch Tomb was first discovered in 1927, when constructing the inter-provincial road 2. A French architect named J. Bouchot discovered a small tall stone slab beside the root of an ancient tree and he conducted excavations over the course of 1 month (from April 14 to May 16, 1927). He published the results multiple times in 1927 and 1929, and described the burial chamber in detail as follows: the burial chamber has a box-shaped structure, 4.20 m in length, 2.70 m in width, 1.80 m in height, assembled from 6 granite slabs, each weighing 10 tons, held tightly together by a grooved system under the tomb cover and bottom slab with 10 cm grooves, 4 to 5 cm deep. The tomb cover was raised and lowered by means of a pulley system using granite columns 7.50 m tall and sandstone columns 3 m to 4 m tall.
In 2011, with approval from the Ministry of Culture, Sports and Tourism, the Department of Cultural Heritage, and the Đồng Nai Provincial People's Committee, the conservation and restoration project of Hàng Gòn Cư thạch Tomb was implemented with the following construction items: preservation of stone architectural components, construction of a protective shelter over the burial chamber, protective fence for the stone-working workshop, administration building, exhibition house, security house, perimeter wall and gate, toilet facilities, internal roads and squares, fire prevention and lightning protection systems, water supply and drainage systems, and lighting system for the entire site, creating the current appearance of the heritage site.
