AUFIDENA, ancient city of the Samnites Caraceni, just north of modern Alfedena, Italy, a station on the railway between Sulmona and Isernia, 37m. from the latter. Its remains are de scribed by L. Mariani ;n Monumenti dei Lincei ( 190 i) , 225 seq. ; cf. Notizie degli scavi (1900, 442 seq.; (1902), 516 seq. The ancient city occupied two hills, both over 3,800ft. above sea level (in the valley between were found the supposed remains of the later forum), and the walls, of rough Cyclopean work, were over a mile in circuit. Fourteen hundred tombs have already been examined in the necropolis below the town, and this may be only a sixteenth of the whole. They are all inhumation burials, of the advanced iron age (7th to 4th century B.c.), falling into three classes—those without coffin, those with a coffin formed of stone slabs, and those with a coffin formed of tiles. The objects dis covered are preserved in a museum on the spot. Castel di Sangro, five miles to the north-east, was probably the post-station on the road between Sulmo and Aesernia in the Roman period.
