ertain archaeological references speak of the presence of defences along the western zone of the castro, some terraces to the side of an access road that leads to the peak, and an accumulation of earth and stone that, while possibly being the result of the construction of the road, could also be the remains of defensive structures subsequently disturbed during road construction. On the western path there are numerous fragments of pottery (common ware, amphorae, tegula…).
The upper part (“croa” measuring approx. 75m x 50m) of the castro, which is filled with granitic rocks (like the rest of the mountain), is very altered due to the erection of a pylon and a mobile phone mast; it is also substantially covered by scrub vegetation (gorse) and some very large eucalyptus trees.
Despite the extent of this vegetation it was possible to record a small hole in which it is possible to see part of a stone wall: it appears to be the remains of a dwelling, of one wall or other type of architecture.
In this same area there is a small elevation or alteration of the land that could be of artificial origin.
There is a large amount of loose stones throughout the upper part of the castro and along the southern slope, which could correspond to collapsed walls (it should also be remembered that the abundance of rocky areas favoured the existence of numerous quarries throughout the mountain).
Due to its siting and topography the site of the castro offers ideal natural defences, with the only artificial defensive structures (possible parapet and terraces) found in the areas with least natural protection through which the access path to the peak passes (S and SW area). The petroglyphs that have been catalogued as located on the croa could not be found due to the vegetation.
