Then, only short words ‘Kampong Thom’. During the French colony in Cambodia, the French ruled and divided Cambodian territory into provinces, and named them according the spoken words of the people called ‘Kampong Thom Province’ until now.

Main archaeological features in these groups of monuments are said to have been founded by king ISANAVARMAN I, the son of king Citrasena. Many decorative details in Khmer architecture and sculpture are classified as Sambor style: the name was derived from these monuments dated in the first half of the 7^th century. Henceforth this kingdom was the leading state and comprised the whole of Cambodia proper. Furthermore, several successions of kings’ reign might have maintained these monuments as their capital city. The century following the death of JAYAVARMAN I who is the last known king of this kingdom in the second half of the 7^th century is a dark period in the history of Chenla. According to a Chinese accounts, in the 8^th century, the country of Chenla was divided into land and water Chenlas. The obscurity prevails and this monument might be neglected thereafter. The history. However, is traced again with the accession of JAYAVARMAN II, who founded a new polity that is now referred as Angkor in the beginning of 9^th century. Decorative details of Prasat Tao (Central Group) are similar to the style of the remains belong to the period of the king JAYAVARMAN II, Particularly, characteristic lion statues resembles the statues found in Phnom Penh. From these reasons this architectural complex is said to be constructed in this period.

Furthermore some inscriptions in Prasat Sambor (Northern Group) are dated in the 10^th century under the reign of the king RAJENDRA VARMANII. And Robang Romeas group that is located about 2km northward from main temple area, contains other inscriptions of the king SURYAVARMAN I period. Some other decorative details and statues belong to the late Angkor period styles were confirmed from these temples. These historical evidences suggest that these monuments must have belonged to the important provincial principle city after Pre Angkor period.

From above historical perspective, this group of monuments is extremely significant not only for Cambodia but also for the entire area of Southeast Asia, for they are the only remaining sound architectural constructions that exemplify the architecture and sculpture of the early period in sizable quantity.
