Two rather strange cave chambers were hollowed out of a single massive rock. One of the chambers is believed to have been the guard room, the rear wall has two straight vertical lines and one horizontal line cut into the rock; this 'doorway' is supposed to lead to king Bimbisar treasury. Inscriptions in the Sankhalipi or shell script, etched into the wall and so far undeciphered, are believed to give the clue to open the doorway. The treasure, according to folklore, is still intact. The second chamber bears a few traces of seated and standing guards etched into the outer wall.
