Rollos complex is one of the earliest large and permanent temples built by Khmer people, marking the beginning of the Khmer classical art era. There are mainly Shenniu Temple, Bakong Temple and Loire Temple. After the vicissitudes of time, these temples have been damaged to varying degrees. Therefore, it can be called the Rolls site, but its tall ruins still do not lose the grandeur of the year, people can still see a different kind of beauty from the ruins, or people did not say that we should be good at discovering beauty, let alone for this ancient building, reveal the classical beauty everywhere.
