• Rubia Tower, in Molinos Marfagones (Cartagena, Region of Murcia, Spain), is one of the fortress towers that were built in the Campo de Cartagena at the end of the 16th century, with the aim of serving as surveillance and protection for shepherds and farmers who worked the lands of the owner of the tower against the frequent incursions of Barbary pirates who landed on the nearby coasts. Therefore, this type of post-coastal towers or strong-houses, also called “repopulation towers”, formed the second line of the system of coastal defensive towers developed during the reign of Felipe II. This tower is privately owned and is in a good state of preservation, although with more modern buildings attached to both sides. It has a rectangular floor plan and a structure of masonry walls that originally had to be plastered in an ocher tone (hence the “Rubia” wording). The current access is through the ground floor of the house attached to the west wall, and to communicate with the two upper floors and to access the roof there is a spiral staircase in the northeast corner. The objective of the work carried out has been to obtain complete digital documentation of the tower by means of digital photogrammetry. The difficulties in correctly developing this work methodology meant that the survey was completed with the use of a drone. It was possible to visually tour the entire building and, with 3D modeling, obtain three-dimensional scale models with hyper-realistic texturing. The result is graphic information that facilitates the formal and constructive analysis of the monument, necessary for an adequate comprehensive restoration proposal. The methodology followed and the results obtained are described in order to contribute to the conservation and dissemination of this Tower.
