In the center, the Tarasin had erected a kind of altar or monument. They said they did not worship there, but instead set up the monument as a celebration of life in the forest.

The Sacred ch'hala tree grove of the Tarasin lays deep in the forests of Cularin. It includes dozens of ch'hala trees, some of them from around 532 BBY. The trees cause hypnotic ripples of color, similar to the effect Tarasins get with their scales.
There is a stone in the middle of the grove, commemorating the time when the Tarasin began living in sedentary tribes or irstats. The stone predated the grove.
At least once in their lives, each Tarasin religious leader would make a pilgrimage to the sacred grove. They would return home with the cutting of a ch'hala tree, to plant near their irstat. The irstat-kes of any Tarasin irstat was supposed to meet there with her peers periodically.
The Tarasin forbid any alien to visit the Grove, with rare exceptions, such as some highly respected Jedi, that occasionally come to this grove to meditate when in great distress.
