[en] In 1999, the aerial photographs taken by Julio del Olmo of several archaeological sites in the Duero valley allowed us to discover the existence of a new Roman building in the area of El Monduengo lagoon. This area is located immediately south of the well-known Roman villa of La Calzadilla, also known as the villa of Almenara de Adaja-Puras, in the south of the province of Valladolid, very close to Coca, the pre-Roman and Roman city of Cauca, whose influence was felt in the pace of Roman expansionism in countryside during the Early Imperial period. In this paper we propose to revisit of one of these oblique aerial images taken by Julio del Olmo, which, despite its oblique perspective, is of great quality. Moreover, even today, it is also the only image to date that shows us the buried remains of this Roman building. In addition, we have explored the possibilities for remote sensing provided by the wide range of publicly available orthophotographs, including historical series such as USAF Series B and the Interministerial Flight. In order to carry out this remote sensing study, we have used the Near Infrared frames recorded alongside the traditional PNOA orthophotography in the visible RGB spectrum. Using both RG and NIR bands we calculate vegetation and soil indices; these indices employ chiefly the Red and Near Infraed band of the electromagnetic spectrum. This remote sensing work has been carried out only with public images and open-source software (QGIS, R Project, SNAP). The study of the graphic documentation has led us to carry out a geophysical survey using Ground Penetrating Radar (Noggin 250 mhz). This way we obtain an updated and accurate image of the extension and morphological characteristics of the new building. This work is carried out in order to improve our understanding of the evolution of the Almenara de Adaja-Puras site from the end of the Late Iron Age to the Late Roman period. In addition, we compare this building with some other structures of a similar type known both at the La Calzadilla site and in other sectors of the Duero Valley.

[eu] Julio del Olmok 1999an airetik egin zituen argazkiei esker lehen gertu-gertutik ahal izan dugu El Monduejo (Puras, Valladolid) putzuaren alboan ustez erromatar garaikoa den eraikin bat dagoela. Eremu hori La Calzadilla erromatar hiribilduaren hegoaldean dago, Almenara de Adaja-Puras erromatar hiribildua izenarekin ere ezagutzen dute eta Valladolid probintziaren hegoaldean dago. Cocatik (Segovia) oso hurbil dago, garai aurre-erromatarrean eta erromatarrean Cauca zena, eta ziurrenik eragin nabarmena izan zuen Erromako goi-inperioaren garaian landa-eremuko lurrak kolonizatzeko erritmoan. Lan honetan, Julio del Olmoren aireko irudi zeihar horietako bat berrikustea proposatu dugu. Izan ere, perspektiba gorabehera, kalitate handia du eta, gainera, 2020ra arte eraikin horren lurperatutako zatiak erakusten zituen bakarra da. Bestalde, eskuragarri dauden eremu hartako ortoargazkien sorta zabalak eskaintzen dizkigun teledetekziorako aukerak aztertu ditugu, sorta historikoak barne, hala nola USAF B Sorta eta Ministerio arteko Hegaldia. Ikerketa hau egiteko, fotograma infragorriak eta RGB espektro ikusgaian ateratako PNOA ortoargazki tradizionala erabili ditugu, banda Gorriek eta Infragorriek gehien erabiltzen duten landareen eta lurzoruaren adierazle-sorta kalkulatzeko. Teledetekziorako lan hau irudi publikoekin eta open-source softwareekin (QGIS, R Project, SNAP) soilik egin dugu. Dokumentazio grafikoaren ikerketak eraman gaitu georradarrarekin (Noggin 250 MhZ) azterketa geofisikoa egitea planteatzera, egungo irudi zehatz bat lortzeko eta eraikin horren hedadura eta morfologia hobetu ezagutu ahal izateko. Lortutako datuei esker hobeto uler dezakegu Almenara de Adaja-Puras aztarnategiak erromatar garai berantiarrean, K.o. III. mendearen ondoren, izan zuela bilakaera. Gainera, egitura hori antzeko beste batzuekin alderatu dugu, bai La Calzadilla aztarnategi bertakoekin bai Duero haranekoekin.
