The restoration of a portion of the Etruscan walls that delimit the Archeological Area was one of the works to be undertaken.
Roots were pushing on them, causing some ashlars to be ejected and causing, in turn, the adjacent ashlars to jut out from their original spot for up to 30 centimetres, on the verge of falling.
One of the ashlars was severely fractured and was mining the stability of the entire upper portion of the wall.
After shoring up the adjecting portion, we could proceed with the dismantlement of those ashlars, the implementation of a superstructure made of bricks — that we then proceeded to plaster, in the attempt of making the restoration work less obvious — and the relocation of the ashlars in their original spot.
The fractured ashlar was consolidated by inserting two fiberglass rebars with improved adhesion.
The podium of the Roman temple was manually weeded by the use of scalpels and toothbrushes. Then it was preconsolidated by the use of a silicate based product additivated with a slow-release biocide.
After twenty days since the treatment will be over, we will proceed with the plastering of the crack pattern and of the edges of the spalling surface. This a preparatory intervention for a following adhesive consolidation that it is recommended to be planned as soon as possible.
Restoration works have started on the three podia, whose marble surfaces are heavily attacked by microorganisms, whose diffusion is facilitated by the widespread decohesion of the stone. Here it's quite evident the phenomenon called interference — a change in color occurring during a biocidal treatment. It is a temporary side effect caused by the the microorganisms releasing substances as carotenoids and melanins; it will disappear in few days.
Weeding treatments are now completed and the structures of the Sacred Area are finally clearly revealed, in particular the ones located in the Southern slope and the ones on the paving, where the a portion of the gutter is now restored.
In the meantime we completed the restoration works on two Longobard tombs: one is located within the Etruscan temple, while the other one is located in the Longobard Necropolis area.
Now everything is ready for the architectural survey!
