The ancient town located at Alto de Rodilla (Monasterio de Rodilla, Burgos, Spain), identified as Tritium Autrigonum, has never been the subject of an archeological excavation, although the site has been known for a long time. However, the aerial survey campaigns conducted between 2001 and 2015 made it possible to take a large number of photographs that expose the urban form of the city. They reveal, on an unprecedented scale, a significant portion of the buried structures throughout the agglomeration. After a brief presentation of the site and the extent of our current knowledge, this work details the exploitation of the rectified and georeferenced aerial views, making it possible to obtain an unedited planimetry of the remains. It also provides an exceptionally detailed description of the site. This expanding documentary base was used in 2016 to study the remains identified as monuments. Since then, the analysis of the analysis of the aerial photographs has made it possible to obtain a general plan of the city, the various facets of its urbanism in its various aspects and to situate the city within the urban spaces of the northern Hispanic area.
