The traces that are preserved nowadays don’t seem to represent a defensive bastion. The “Croa” is protected by just one wall which doesn’t covers all its perimeter, but has its wholeness and bigger scope in the half-south where it has a very pronounced external slope with a height in some of its sections. This can be appreciated in the right wing of the door where the defensive wall rises to one of its highest heights, not only outwardly, but also in the interior parapeto with thr most 4:30 m. The remaining defensive wall will lose weight to such an extent that the North side can’t almost be seen from the inside as it is on a level with the ground. In this area, the lie of the land itself, which slopes over the village of “A Xerpe” contributes to the inaccessibility without being necessary to build additional defensive construction sites.

While the opposite side is more horizontal and contains the need for building important defensive walls with loads of land covered with stone and slab. This a material which appears in bin quantities inside the walled enclosure itself. Waiting and bracket which is visible in some of the sections of the wall.

The defensive construction sites must have been done with the pits, which surrounded some parts of the place, and with the passing of time they were used as paths for wagons and service of farmland. The defensive wall which was in the west has a continuation which must be the only entry to the interior of the hill-fort.

The interior of the “Croa” or “Groia” is tumular shaped (the highest central part falls down in a small slope in all directions, while there is some kind of passage which surrounds all the interior in its lowest part)...
