Jaherthan

Jaherthan, also known as Jahirathan or Jahergarh (Hindi: जाहेरथान, जाहिराथान, जाहेरगढ़), is a sacred grove that is considered the residence of Jaher Ayo and is a worship site for the Santal, Bhumij, Paharia and Bedia tribes in India and Bangladesh. It is a characteristic feature of Bhumij and Santal villages, typically located on the village's outskirts, where many holy spirits reside and where a series of annual festivals take place. The grove is designated during the village's founding and remains undisturbed except during festivals. Inside the grove, a series of uncut stones represent the Bongas (spirits), for which they are not considered substitutes except during festival rituals.
