The Rollos group includes the Rolex Temple, the Holy Niu Temple and the Bacon Temple. The Rollos group was built in the late 9th century and is known as the beginning of Khmer art. The founder of the Angkor dynasty, Jehomah II, established several capitals, the second Rollos, and the Angkor dynasty is set to be 70 years old. The temple group is relatively large and is one of the important monuments of Angkor.
