Rock art of the Mediterranean Basin of the Iberian Peninsula was declared World Heritage Site by UNESCO, it has an outstanding cultural value hence its dissemination is essential. Over the years, rock art paintings have been deteriorated and even some have disappeared. Consequently, it is quite difficult to recognise them in situ without experts. At this point, non-invasive and novel techniques can offer great potential, on the one hand, avoiding direct contact with the surface promoting its conservation, and on the other hand, through dissemination and analysis of these elements. One of the most promising techniques is Augmented Reality (AR). By means of AR applications, the visitor can see any kind of virtual content related to cultural heritage, through its mobile or tablet screen. Thus, any virtual content that is considered of interest can be added, offering in this way additional information that complements the real element. In this study, two approaches are presented for the rock art dissemination of the Cova dels Cavalls. The first is based on a marker recognition, which launches the application that displays an image of the motif and a descriptive text about it. In the second proposal, the camera device recognises the real image of the painting and the virtual information is overlapped. The study aims at evaluating the use of these AR techniques applied to rock art dissemination and shows the methodology for its development.http://dx.doi.org/10.4995/CIGeo2017.2017.6598

Archaeological cultural heritage is a precious resource that should be transmitted to future generations. The 3D digital representation of monuments and sites has proven to be a reliable method for this aim. This article shows the geomatics workflow undertaken for the complex rock art documentation of the Cova dels Cavalls (Tírig, Castellón). The paintings are part of the Rock art of the Mediterranean Basin of the Iberian Peninsula declared a UNESCO’s World Heritage Site in 1998. The various stages are reviewed, from the acquisition phase up to the delivery of part of the derived metric products, such as 3D models and photorealistic models.http://dx.doi.org/10.4995/CIGeo2017.2017.6627

New Evidence

The Brú na Bóinne World Heritage Site, Ireland is best known for its megalithic monuments, in particular the great developed passage tombs of Knowth, Dowth, and Newgrange, and its abundance of megalithic art. However, our understanding of the wider Brú na Bóinne landscape has changed beyond all recognition in the last decade owing to the application of modern, non-invasive survey technologies – in particular LiDAR and large-scale geophysical survey – and most recently as a result of the hot, dry summer of 2018 which revealed a series of remarkable cropmarks between Newgrange and the River Boyne. Despite a lack of excavation it can be argued, based on their morphological characteristics, that many of the structures revealed belong within the corpus of late Neolithic ritual/ceremonial structures, including earthen henges, square-in-circle monuments, palisaded enclosures, and pit/post-alignments. These display both extraordinary diversity, yet also commonality of design and architecture, both as a group and with the passage tombs that preceded them. This paper provides an up-to-date survey of the late Neolithic and presumed late Neolithic landscape of Brú na Bóinne. It provides new evidence and new insights from ongoing survey campaigns, suggesting parallels within the British Neolithic but also insular development within some monument classes.

The Impact

Abstract. The impact of changes in agricultural land use and practices as a controlling driver of hydrologic response and as a source of diffuse pollution, are studied in the Joumine River basin, discharging into the Ichkeul Lake, northern Tunisia, a UNESCO World Heritage site since 1979. The lake is characterized by a very specific hydrological functioning based on a seasonal alternation of water levels and salinity through its link to the Mediterranean Sea. Three Landsat images, in situ surveys and SWAT modelling were used to simulate and assess streamflows and nitrate loads under retrospective land uses.

The City

&lt;p&gt;The city of &amp;#201;vora, a World Heritage Site recognized by UNESCO in 1986, also owes this recognition to the stones that built its monuments and preserve them until today.&lt;/p&gt;&lt;p&gt;This work brings together the contributions that we have gathered over the past three decades and allow us to have a very complete idea, not only about the materials used in the hundreds of monuments and historic buildings but also about their provenance. If some materials are so emblematic that they allow an immediate identification with the naked eye, others needed more sophisticated and precise techniques so that there was no doubt about their origin.&lt;/p&gt;&lt;p&gt;The igneous rocks and gneisses of granite composition are part of the &amp;#8220;Massif of &amp;#201;vora&amp;#8221; on which the city is built. Thus, and quite naturally they are by far the most represented group in monuments from all historical periods. Its function is essentially structural, but there are also functional, ornamental and decorative objects. For example, the oldest megalithic structures found in the vicinity of the city are made up of large granite blocks that often had to be transported to their locations.&lt;/p&gt;&lt;p&gt;On the other hand, many gargoyles and statues that decorate the churches are also made up of these granite rocks. On these, the natural erosion of centuries of exposure to the environment has led to a state of alteration, sometimes very accentuated, which would justify its replacement by replicas sculpted in similar rocks. Provenance studies have made it possible to identify old quarries in the vicinity of the city where, on the one hand, the ancient rock extraction techniques can be observed and on the other hand, they allow the obtaining of the raw material necessary for these restoration and conservation works. In any case, they are places that need to be inventoried and protected, with the municipality already aware of their existence.&lt;/p&gt;&lt;p&gt;As well as the monuments of the Roman Period, also the structures of the Medieval Period, such as the city walls, the Cathedral (started to be built in 1186 AD) and all the great churches, were also built with these granitoids.&lt;/p&gt;&lt;p&gt;In addition to these rocks, many others of multiple varieties and origins are present. The marbles, especially the Estremoz Marbles (Global Heritage Stone Resource), are ubiquitous in the city, but there are also emblematic marbles from other places, some easily identifiable (ie Viana do Alentejo, Escoural, Trigaches, Serpa and Vila Verde de Ficalho, for presenting mineralogy, textures, colors and patterns which, together with more recent analytical techniques, have confirmed its provenance.&lt;/p&gt;&lt;p&gt;Sedimentary rocks, with emphasis on Portuguese Mesozoic limestones, ie Lioz - GHSR and Brecha da Arr&amp;#225;bida - GHSR candidate, among others more rare and with very specific use in ornamental details, are also present and contribute to enrich a heritage in stone that makes this city so special and very popular with tourists of all nationalities.&lt;/p&gt;&lt;p&gt;Acknowledgments: the authors thank to FCT for funding the ICT (UID/GEO/04683/2019), as well as COMPETE POCI-01-0145-FEDER-007690.&lt;/p&gt;

<p>The Bach Dang Bridge forms part of the Ha Long – Hai Phong Highway in Vietnam. It will help cut 50km from the journey between Hanoi and the Ha Long Bay UNESCO world heritage site. The focal cable-stayed section of the bridge will consist of two main spans of 240 m. The tallest of the three towers will reach a height of almost 100 m.</p><p>The construction technique used for the cable-stayed section is to cast 9.6 m-long and 28 m-wide concrete segments in situ, using an underslung form traveller (FT) which is launched to the next position once the segment is cast.</p><p>The FT has been designed by the Technical Centre of specialist contractor VSL. Its weight is minimised by using the stay cable as a support at the front of the traveller. The stay cable is connected to the FT by precasting the anchor block and securing it to the FT. This innovation was previously, successfully used by VSL on the Ironton-Russell project in the USA. Besides, the formwork system has been mechanised to be easily collapsed from one segment to the next.</p><p>This paper discusses the design of this innovative construction technique and how it was used on this major bridge project in Vietnam.</p>

ABSTRACTThe Museum of the Great Temple of Tenochtitlan in Mexico City holds a collection of several thousands of polished stone artifacts that were excavated and identified as temple offerings. These can stratigraphically be related to the sequential construction stages (II-VII) of the ceremonial area of the Aztec capital from the foundation of the city in 1325 to 1521, when the Spaniards conquered the city. A non-destructive investigation of the elemental and chemical composition of these archaeological artifacts helps us to understand the provenance of these pieces, their use and the specific mineralogical choice for these artifacts as well as more information regarding trade routes relevant to the development of the Aztec empire. A mineralogical analysis of, in total, 450 stone artifacts was carried out using infrared spectroscopy (FTIR) and X-ray Fluorescence (XRF). From this, eighty-five pieces were selected according to their excavation location, either in the Great Temple itself or in the surrounding buildings, as well as to represent the different construction stages of the area (this is part of a World Heritage Site). The resulting mineralogical and chemical information was related to possible mineral resources that were controlled and used as the empire expanded. Artifacts made from high-status semi-precious minerals, like jadeite and turquoise, are found to be concentrated in the central buildings and in the Great Temple itself, but also in the later construction periods of the area.
