Elevation and ground plan of the Roman Alconétar Bridge in Cáceres Province, Spain, according to Fernando Rodríguez from November 1797. The diagram shows the remains of the bridge at the time and, in weaker shades, the reconstruction attempt by Rodríguez. The two original drawings, after which the diagram is modelled, are in the Gabinete de Dibujos de la Real Academia de Bellas Artes de San Fernando in Madrid, Spain (signatures A-3638 and A-3639).
