To the right of the entrance there was a defensive tower where the walls narrowed, so it is assumed that it was shut with a gate to prevent the passage of carts.

There is a sloped entrance that leads into the interior living space, which is divided into four separate parts.

Within this building a fireplace, some earthenware artefacts and a hole for a post were found, indicating it could have been a forge.

The subsequent excavations were carried out by J. M. Luengo (1969-1970), Francisco Calo Lourido and Teresa Soeiro (1980 to 1984).

Ánxel Concheiro (1984) and Francisco Calo (1985) reinforced the structural integrity of the fort, and a new round of excavations and renovations was started on May 21, 2012.
