Abstract
The Archaeological Area of Majadaiglesia is located in the comarca of Pedroches, in the municipal term of El Guijo, to the north of the province of Córdoba. The abundant archaeological and epigraphic remains lead to the hypothesis that Majadaiglesia can be Solia, a completely romanized multicultural settlement in the last quarter of the first century.
In this vast site of about 19 ha the remains of a wall, many hydraulic structures and a necropolis from Roman times are observed. With view to future archaeological activities 3.7 ha site were investigated by geophysical surveys, which 1.3 ha correspond to plateau Cortijo Majadaiglesia, and are forming the subject of this study.
Geophysical exploration work consisted of a topographic survey of the study area, a magnetic survey, and a survey with subsurface radar (3D) in sectors where the magnetic survey had identified anomalies of interest.
By combining both methods have been identif ied a number of underground structures that have established that most of the structures are linked to hydraulic constructions. Moreover, the good dielectric contrast between the buried bodies and the enveloping material it has favored the application of a ref ined treatment to one of the structures detected with GPR, so have been able to generate images with suff icient quality for its archaeological interpretation, based on comparison with similar structures excavated elsewhere.
