This archeological site is also important for Southeast Asian Studies. It was first discovered in 1985 and has gone through three excavations. You'll see several temples and tower-shaped graves belonging to an extinct kingdom. Although this kingdom ended 13-14 centuries ago, its remains reveal alot about the existence and the disappearance of this mysterious kingdom.

The largest vestige area on this site is the Doc Khi (go 1A) Temple. It is located on the highest hill of the site and faces east. Archeologists have found Linga and Yoni statues in this tower-shaped temple-believed to be large votive objects reflecting the harmony of yin and yang.

Locals are known to fetch water at the temple and pour it over the two statues to pray for a pregnancy. If a girt is desired, the worshippers placed their hands on Yoni; if a boy is desired, they touch Linga. Afterwards, they drink some water that flows on Yoni to fulfill their wish.

Near 1A Temple are some smaller temples. One of most beautiful ones is located close to the river and is surrounded by a wall.

Since 2001, Da Lat Tourist has organized tours to this site. In 1997, the Cat Tien Vestige Site was recognized by the Ministry of Culture and Information as a National Vestige Site.
