<p><strong>Abstract.</strong> The Negro Tower or Arráez Tower, in El Algar (Cartagena, Spain), dates from 1585. This tower was part of an extensive network of watch and defense towers built along the coastline of Murcia between the sixteenth and seventeenth centuries. It is an inland rural tower, in visual contact with the coastal towers. Its objective was to receive and transfer warnings from onshore towers to protect the population, especially farmers. The tower is protected as a monument but is currently in a dilapidated state of conservation. Therefore, this building has been chosen as the object of an integral study, which can serve as a reliable basis for its correct conservation and restoration. Through historical analysis, light has been shed upon the evolution of the Tower from the social, cultural, and architectural points of view. The graphic documentation has been made using digital photogrammetry and a 3D laser scanner, compatible with classical topography. Based on all this information, an integral project of consolidation and volumetric recomposition of the tower has been proposed. As a result of this research, we intend to contribute to the conservation and recovery of the heritage value of the Tower, as well as the integration of the historic monument in its natural environment.</p>

<p class="VARKeywords">The accurate graphic survey of an archaeological site is fundamental for its analysis and research. Furthermore, if this site is to be covered by a building and will not be accessible or visible, its documentation is essential, not only to continue with the research, but also to disseminate and enhance the discoveries. An example of this is the "<em>Hoya de los Molinos</em>" archaeological site in Caravaca de la Cruz (Region of Murcia, Spain). This is where the first mark of the wheel of a Roman vertical watermill in the Iberian Peninsula has been found. This fact is crucial because remains of Roman vertical-wheeled watermills have been found across the Mediterranean but not in the Iberian Peninsula. Moreover, the fact that this watermill still has all its structural elements makes this archaeological site in Caravaca de la Cruz very interesting. Due to these facts, it is essential to disseminate this discovery, so that it can be recognized and considered as archaeological and cultural heritage. To that end, the researchers have carried out a three-dimensional (3D) reconstruction of the most characteristic elements, such as the vertical wheel, the gears that allowed grinding the grain, and the building protecting them. A virtual recreation was carried out, based on the historical and building research, which is displayed in an explanatory video. Furthermore, two reproductions were created: one made to scale of the archaeological site with a 3D printer and another one of the hypothetical structure of the Roman watermill. To achieve this result, historians, archaeologists and engineers have collaborated, thus enabling not only its adequate dissemination, but also its accurate documentation, in an inclusive manner. Thanks to all the work that this paper describes, the Roman watermill found in Caravaca de la Cruz can be known, studied and assessed.</p><p><strong>Highlights:</strong></p><ul><li><p>The first Roman watermill in the Iberian Peninsula has been found with all its structural elements, from the imprints left in the stone by the wheel.</p></li><li><p>Virtual reconstruction of the first vertical wheel watermill discovered in Hispania has been made.</p></li><li><p>An animated video of the hydraulic watermill gears performance has been created for documentation and dissemination.</p></li></ul>

Se expone la metodología desarrollada en la ETS de Arquitectura y Edificación (ETSAE) de la Universidad Politécnica de Cartagena (UPCT) para la realización de Proyectos Fin de Grado (PFG) en el actual Grado en Ingeniería de Edificación, centrados en el patrimonio arquitectónico. Con la realización del PFG el alumno muestra cómo ha asimilado e integrado los contenidos formativos recibidos pero también debe ser una oportunidad para potenciar las competencias específicas y transversales del título. El texto expone la metodología, basada en la motivación e implicación del estudiante, para desarrollar el análisis integral del edificio histórico y la difusión del PFG. Los resultados obtenidos, después de casi veinte años de experiencia y más de ochenta PFG dirigidos y enfocados a la investigación, el análisis histórico-constructivo y de patologías y la propuesta de intervención, para su futura restauración y conservación, de construcciones históricas; muestran una metodología eficaz para la formación técnica y humana del estudiante, especialmente en el ámbito del Patrimonio Arquitectónico. Una experiencia exitosa si se tienen en cuenta los premios que han recibidos los egresados en reconocimiento a la calidad de sus PFG.

The Atalaya Castle (eighteenth century), in Cartagena (Region of Murcia, Spain). Formal and constructive analysisThe Atalaya Castle (eighteenth century) is one of the military fortifications that were part of the defense of Cartagena. The defensive system of the period was composed of an important walled enclosure, which surrounded the city, the arsenal, and a group of fortresses outside the city wall, located on the nearby hills. One of these defensive constructions is the Atalaya Castle or Fort, located to the west of the city from its position it protected the population from attacks both by land and by sea. To the north and west by land, through the Almarjal and the Pelayo mountains, the south by sea covered the possible landings in the bays of the Algameca Grande and the Algameca Chica. The building is a magnificently construction, the fort has a pentagon ground plan with five bastions at each angle. It has an interior building in U arranged on a solid bastioned platform the whole complex is surrounded by a dry moat. The fortification present certain formal elements used in other constructions that had been lifted in the city at that time, circumstance gave unity to the whole. The materials consisted of employed mainly stone and brick, the constructive elements introduce certain heterogeneity. The purpose of the communication is to present the results of the comprehensive analysis carried out in the Atalaya Castle as well as to contribute, through its dissemination to raise awareness of the need for its restoration and enhancement. Research has studied the characteristics of the formal and constructive system of the fortification currently in a state of semiabandonment, a proposal has also been conducted for a new cultural use as a guarantee of its correct recovery and conservation.
