IOM RAS preserves 55 Old Uighur manuscripts related to a group of Buddhist Uighurs
who were active around the monastery of abita qur “Abita Cave” at the Toyoq Cave Temples. This
paper investigates the location of the “Abita Cave” through Uighur wall inscriptions, which have been
discovered at the monastery complex in the West Zone of the Toyoq site. Furthermore, this paper
inquires into an Old Uighur toponym mentioned as the hometown of the scribe of one of the 55 manuscripts,
which would suggest the pilgrimage range surrounding the Toyoq Caves.
