| The Governing Board approves the award of the cleaning and restoration works for 38 meters of the Andalusian defensive route | The Government Board has approved the awarding of the cleaning and restoration works of the archaeological remains of the wall located on Calle Sagasta.This is the first step to carry out the enhancement and musealization of this space that currently remains in the basement of the building on Calle Sagasta, and which was exhumed in 1997.After an excavation process where various structures overlapped, a part of the Andalusian defensive layout with a section of wall and antemural have been preserved.
The remains of the defensive system to be preserved are about 38 meters long, and communicate with the remains of the same wall, preserved in the open air.Currently this archaeological zone presents a pathology with two important damages:1.- Pollution dirt: Presence of black crusts in the form of patinas, hundreds of chemical compounds are emitted directly or indirectly into the atmosphere due to urban activity.2.- Vegetation: The remains are in an orientation that does not allow the sun to arrive for a long time.
This causes the humidity of the remains to be about 3 meters deepThe project consists of defining the necessary actions for the restoration, reconstruction and volumetric reintegration of the archaeological remains belonging to a section of the Andalusian wall, tower and antemural of the basement located in Calle Sagasta.The priority of this project will be the restoration of the verticality of the section of the demolished wall, designing a global survey system for the remains, and a reversible conservative restoration, selecting current and innovative reintegration materials as well as traditional ones.Along with the conservation and reintegration of the archaeological remains, action will be taken on the drainage and control of both groundwater and the building's sanitation system, to improve the site's conservation system, preventing flooding from the ground again.The use of materials related to the original ones, such as lime and lime water, will be a priority, both for the consolidation of the degraded layers and to reconstruct the missing parts that give stability to the property.
These materials have been studied and tested in the urban archaeological sites of Murcia and the Region of Murcia, as an example the Site of San Esteban having demonstrated its stability.The cleaning of surfaces of the remains of the wall and pre-wall will be dry with suitable instruments, with non-invasive techniques.The level of dry cleaning can be increased on the surface of the wall and arrow slits, with a wet cleaning with water vapor projection, since they are determined as suitable surfaces to withstand this procedure, due to their resistance and hardness.After the cleaning process and as protection of the archaeological remains against a biological attack, of plants or mosses on surfaces, a biocidal and herbicidal treatment will be projected by application by spraying a broad spectrum product.The electrical installation will be carried out with halogen-free conductors under PVC pipe, preferably traced by the basement ceiling, and the lighting will include waterproof luminaires and emergency LED luminaires.It will also be equipped with two watertight decorative projectors, for the purpose of achieving visualization from the outside of the section of the recomposed Wall.Once the lost elements have been restored and the Andalusian defensive remains have been fully preserved, the musealization of the entire space will be contemplated, with a modern expositional speech, which can be visited, with the highest degree of accessibility and with sustainable maintenance.The works will be carried out by Arqueonaturaleza SL, for an amount of 66,922 euros and within a period of three months.Enhancement of the outer wallIt must be remembered that the Governing Board of April 17 gave the go-ahead to the project and specifications to contract the work to enhance the archaeological remains of the wall located in the urban scene of Sagasta street.This action is comprehensive in nature and affects both the remains seen and those conserved under the building, as well as the urban space connecting both spaces, making it the space that can be visited throughout the complex and rearranging the urban scene.The project includes actions to eliminate inappropriate elements such as concrete railings and low walls, as well as the pertinent restoration, reconstruction and volumetric reintegration.
