When the local archaeological inventory was being done (Inventario arqueológico del concejo de Ibias) in 2000, José Antonio Ron Tejedo indicated that this site existed. Between 2013 and 2015 various studies have been carried out, including aerial photography, LiDAR, topographies, archaeological surveys and sondages.
A Granda das Xarras is located in the limit between the municipalities of Ibias and Candín. It is a rectangular 5.5 Ha enclosure with rounded corners, and at 1370 m altitude. The perimeter is marked by a fossa and an embankment which can be easily traced around most of the camp, except for those places were entrances had been, and some minor later alterations brought about my more modern dirt tracks and the provincial limit. All four corners presents larges tones in the corners, which were possibly used for reinforcement. The only topographical feature to be found in the interior is an area which has been used for fires, and two small fens which reveal the closeness of the water table.
The defensive perimeter was excavated, uncovering the 40 cm deep and 1.2 m wide v-shaped fossa (ditch) adjacent to an embankment formed with the extracted material. Carbon 14 dating of the organic remains in the fossa indicates that around the transition to the Christian Era the ditch was already filled.
Field surveys at A Granda das Xarras have rendered some iron objects, most of which were very fragmented or warped out of shape, and nails. We can highlight a lance tip and a socket (metallic sleeve for the bottom of the lance), which still had remains of the ash wood used for the shaft.
