On the south-east side of the second Phase fortification we find an entrance (US 14). There is an inside splay and it is 1,5 meters wide. In the door jamb we discovered two holes for a pole to close the door.
There is also a flat plan, maybe a doorstep.
The structure is surely the entrance of the Third Phase castle to go in an open space with a ground floor made in yellow ground (US 12) that cover the slope wall realised in the phase one.
In the photogallery below is a reconstruction plan that mimics the gateway to the castle from the south-east.
Reconstruction, maps, is based on the actual layout of the wall remains unearthed in the excavation. In high contrast, the design is the result of a reconstructive hypothesis that takes inspiration from the archaeological and iconographic data from other contexts (see page "reconstructive hypothesis").
Closing the door:
The port identified in Castiglioncello del Trinoro apparently closed by a door with two sides. To ensure the closure of the door was universally used a wooden cross bar that contrasted in the masonry of the jambs. Sometimes the bars could be two, as seems plausible in our case. To open the door the bar could be placed in a long allocution side or be removed in our case we choose the second option because of the presence of the pair of side holes.
