In the municipality of Íllora, more than a hundred sites from Roman times have been found and, among them, after carrying out an emergency archaeological excavation in house number 12 on Ayllonas street, remains of a Roman thermal complex have been unearthed . This finding provides evidence of the Roman origin of this population.
The complex found has several levels of construction, with pillars and arches, a boiler in good condition, tessellated mosaics in black and white and three pools with drainage pipes, all delimited by strong walls sixty centimeters thick.
There are no remains that allow us to know with certainty the origin of the baths, but the remains of the mosaic of tesserae and some ceramic fragments found seem to indicate that it would be in the High Imperial era, and the abandonment of the baths would correspond to a not too distant moment. , mid-2nd century AD
The knowledge that is had of these baths is very partial, leaving many open questions pending resolution, but it contributes to give an idea of the cultural importance of this municipality.
