Rural, in a woodland at the base of the hill where the Fortified Village is. It is an indigenous fortified sanctuary.
The authors believe it is an inscription of ethnic content related to the Fiduneae and a local deity, Cosunea, equivalent to Mars.
It is an inscription recorded in an oval granite block, artificially cut to receive the inscription dedicated to Cosunea, the deity of the Fidueneae: «NUMIDI1 COSUNEAE/ FIDUENEARUM/ HIC/ LUBENS?/ F(IDEM)/ S(OLVERUNT)».
