<p class="VARKeywords">One of the main objectives of heritage management policies is to promote measures aimed at the maintenance, restoration and enhancement of cultural and archaeological assets. To guarantee this, the responsible institutions must promote actions for the dissemination and transference of cultural heritage, as well as promoting actions with the greatest possible rigour, developing scientific and technical studies that support and improve intervention methods. Recent technological advances in fields such as photogrammetry, digital terrestrial scanning and 3D modelling have made a significant contribution to the digital preservation and dissemination of architectural heritage.</p><p class="VARKeywords">European administrations, in their desire of regional development, as well as the central or local governments have notably boosted the recovery of their rich and diverse heritage. A particular case is Priego de Cordoba’s Castle, a stronghold which was one of the most important monumental icons of the Andalusian period.</p><p class="VARKeywords">Currently, this site is the main target of many architectural interventions and a model due to the implementation of last generation techniques in digital preservation. The local archaeological department promotes a large number of interventions and archaeological excavations. This has made a priority to get a qualitative geometrical 3D documentation, and therefore a constantly updated the point cloud (xyzRGB).</p><p class="VARKeywords">This paper is focussed on presenting the results of the digital preservation process through 2D planimetry obtained from photogrammetric technics, 3D models, and geospatial data. These techniques are a previous step to large architectonical intervention planned in Priego de Cordoba’s Castle, in particular, the identified structures as Wall 1 and Tower 1.</p><p class="VARKeywords">Two out of the three studied structures can be found in Wall 1. They correspond to a cobblestone pavement located in the rampart of the Wall 1, which is a post-medieval period; a double-stepped semi-underground path, excavated in the infill of the wall. The third structure studied in this paper consists of a well, which drills vertically the infill of the wall of the Tower 1. This feature is interpreted in the last research as a vertical well to place the weights of the clock sited in this tower until the 19th century.</p><p class="VARKeywords">This work combines two techniques of geometric documentation to obtain a more complete point cloud. The terrestrial laser scanning, and the photogrammetry due to the higher colour performance, along with the completion of the point cloud obtained with the laser scanner. Along with this study, we will analyse the features which will better define the best technique to fit the documentation of the different structures. Their geometric characteristics, the incidence of sunlight or the accessibility will condition the use and choice of the technique.</p><p class="VARKeywords">We have stated that there is software nowadays which makes it easier to access and consult the information through new computing hardware. Besides, we have highlighted the importance of knowledge and synergy from the different stakeholders implied (city council, technological centre and private companies). The final goal consists of making the society aware of the capital importance of digital preservation as well as dissemination of science.</p>

Technological advancements have a great impact on the dissemination and understanding of the cultural heritage reality due to innovative techniques. These innovations are based on high-precision and high-resolution technologies that allow for the geometric documentation of any object within the fields of history and the arts. Through these techniques, new proposals may be studied and objects can be placed in any historical context. Three-dimensional (3D) digitization allows one to obtain a digital 3D model, which can be handled virtually and recreated at any historical period, enabling the conservation and safeguarding of cultural heritage. Society currently demands new visualization techniques that allow interacting with architectural and artistic heritage, which have been applied in numerous virtual reconstructions of historical sites or singular archaeological pieces. This project allowed us to geometrically document a reused piece with two surfaces (shield and columns) and a plaque of the city of Merida using a structured light scanner from a theoretical-practical perspective. The 3D virtual reconstruction of the pieces was accomplished within this study. The generation of QR codes enabled the interactive display of the heritage pieces. Likewise, a proposal was made to reuse the aforementioned pieces through virtual archaeology. The initial hypothesis is based on the possible existence of a Visigothic niche as an original form. This research reports significant advances in the conservation and exploitation of cultural heritage.

<p>La emblemática almazara Puente de Tablas situada en Priego de Córdoba se ha perdido con el paso de los años debido a las diferentes obras de urbanización y reconstrucción realizadas en la zona. Este artículo resume tanto el estudio de la ubicación como de la reconstrucción virtual 3D de todos sus componentes constructivos y funcionales, valiéndose del descubrimiento del plano inédito conservado desde 1802 –época en la que la almazara aún estaba activa– en el <em>Archivo de la Real Chancillería de Granada</em>. También se hace uso de: (a) los escasos restos que aún perduran, (b) los estudios arqueológicos realizados en esta ubicación, (c) construcciones similares en comarcas cercanas, así como de (d) las últimas técnicas de levantamiento de patrimonio cultural existentes realizadas con escáner láser.</p>
