The castle of Dolceacqua has split stone masonry or mixed with pebbles, bricks and lime mortar. In different rural areas, although the different construction periods masonry texture belong were present common including stone weathering, erosion damage of mortar joints, presence of biological attack for the moisture introduced directly into the wall and to the inefficiency of systems for the collection of rainwater. Landslides, cracks, lesions, gaps and shortcomings were quite widespread. Regarding the plaster layer (uncommon) the deterioration could identify as DT and bulge and black crust.

Many had signs of instability in construction; extensive and alarming were the phenomena of warping, garish wall collapses and injuries, affecting primarily the upper rampart requiring static consolidation work. To counter the bulge of the portion of the wall which joins the main courtyard with the bastion of Savoy (before the area most at risk), had been previously prepared a mesh created with innocent tubes anchored to the masonry. That portion of masonry, formerly covered by vegetation and now totally recovered, had the phenomena of erosion and disintegration, extensive fracturing-cohesion, lacks. Problems maybe due to uneven terrain or lack of or bronzed joint between walls of masonry itself with those of the body close. Everything was aggravated by moisture penetrated that weakened the strength of the wall.

The main restoration operations provided for intervention were as follows:

1) the rivellino towards Porta Lu; 2) the portion of the building collapsed near the new belvedere garden; 3) the “Vela” North; 4) the bastion of Savoy (until new garden and part towards the outside courtyard).

In particular the main interventions were as follows:

- external masonry restoration, stone even receives any portion of bricks, or mixed covered in disseminated form or punctual from plaster, through the following; - elimination of vegetation present (and any roots), removal of incrustations, biological patinas, efflorescence, superficial deposits and worn parts with the aid of brushes, scrapers and/or with suitable mechanical means; hand brushing and deep cleaning of the stone surface with cold water mixed with biocide; - filling of joints with lime mortar including integration of matter at holes and missing parts with materials of the same type, shape and color of existing ones including localized consolidation. - For the bastion, partial substitution of very degraded stones with those found during the excavations. - Internal masonry Restoration, certainly less compromised by infiltration of vegetation, through the following main operations: o elimination of localized molds, removal of incrustations, biological patinas, efflorescence, superficial deposits and worn parts with the aid of brushes, scrapers and/or with suitable mechanical means; hand brushing and deep cleaning of the stone surface with cold water mixed with biocide; o filling the joints with lime mortar included the integration of matter at holes and missing parts with materials of the same type, shape and color of existing ones. Possible replacement of very degraded stones with those found during the excavations. - Restoration masonry inside door Lu and the portion of the building near the new belvedere garden, certainly newer and better preserved, through prevailing cleaning operations: o filling the joints with lime mortar included the integration of matter at holes and missing parts with materials of the same type, shape and color of existing ones. Possible replacement of very degraded stones with those found during the excavations. o filling the joints with lime mortar included the integration of matter at holes and missing parts with materials of the same type, shape and color of existing ones. - Redevelopment of the LU, by means of a stairway to the Barbican and retrieving the current ticket office (to navigate inside the Castle) further notice in exhibit space connected to the Castle (the anticipation of the value to be discovered with the visit). - Elimination of the existing gate near the Leads Lù to allow tourists access to the main Lookout and the new grounds in the framework of the project. - Creation of a public garden-natural viewpoint to redevelop the space now abandoned at the foot of the Castle and of great value to the overall attractiveness of the monument (fundamental is in fact in this context working primarily on the edges/edge), including the restoration of the building's masonry collapsed. - Improve the present belvedere through the replacement of existing railings and placement of a new door that strengthens the concept of "fortezza-baluardo difensivo" and help improve the closure of the Interior which today suffer from the lack of permanent closures (also for obvious reasons of maintenance and enhancement of showrooms). For the same reason removable closures are planned for the two tall Windows of the entrance. - Moving the head from the south tower to the north sailing (where they even moved the technological systems) and retargeting of the North and South towers for permanent display, so anticipate the layout of the Castle. In the current projection room is provided for the relocation of the ticket office with book-shop, selling local products of excellence, adjacent to the system of services. In the future, through this room you can access the gallery system access vertical link that will connect the floors of the Castle up to the level of the current Conference room. - Replacement of wooden window frames with new corten steel, including one that separates the North Tower and a wooden floor where there is the exhibition of new construction. - Restoration to operate the fountain through a timer on the system. - Widespread Interventions replacement of banisters (simple type and type with stretched mesh, always made of corten) in order to characterize in a more contemporary and even the monument. - Restoration of the "vela" North through the introduction of a steel walkway required to consolidate, interrupting the length of the wall, the existing masonry. - Creation of a system of linking and walkways between the upper floor of the portico of the courtyard of honour and "ruin" on the edge of the courtyard itself. The vertical connection system, was leaning against the brickwork degraded towards bastion to act as a coupling element of vertical structures necessary link to strengthen and keep standing the wall partly collapsed structurally today strongly affected by phenomena of bulge and disintegration. The scale becomes even partially rebuilding element-consolidation, even symbolic, demolished wall with which it interacts and within which wraps, not making them perceptible by the cour d'honneur. From the outside, the sealing system is light, transparent and consists of corten steel mesh that lets perceive the parties behind the existing masonry, While recomposing in part the design of the prospectus until existing porch. In particular, the existing system of arches is proposed, or clogged with new components that are always hidden and integrated with your existing system. - Redevelopment of the outside of the Castle, which is extended up to the new port located in the existing gate where the drawbridge. Delete the existing gate and construction of a steel walkway with viewpoint directly accessible from the outside when the castle is closed. - Construction of a scale-down of the bastion where the open space has been recovered and performed some digging required to investigate the situation underground, both place the iron slab on which should rest the mullions are indispensable to maintain the existing wall.
