In this conference we will deal with a series of Roman constructions that until now have not been analysed with the attention they deserve and therefore have not been well interpreted. The most recognisable remains of these, excavated in the coastal rock, can be found in the northern half of the Alicante coast in the towns of Jávea, Calpe, El Campello and Alicante (the latter next to the Roman city of Lucentum). A new installation of this type has also recently been proposed at Cape Trafalgar (Cádiz), although with less obvious remains than those in Alicante.
Numerous nurseries are scattered along the coast of the Mediterranean Sea and there is very little evidence of both types of constructions in the same place. In reality, most of the nurseries were part of sumptuous maritime villas, an element that made them stand out as an expression of maximum luxury and ostentation.
The scarcity and uniqueness of these Roman constructions on the Iberian Peninsula, even with their remarkable monumentality and almost all of them grouped together in a very specific stretch of the Spanish Mediterranean coast, are strong arguments for proposing measures for their conservation. In recent years we have witnessed the partial destruction of some nurseries in El Campello due to marine erosion and others, for the same reason, are in danger of disappearing.

The Roman city of Regina is currently located in the vicinity of the municipality of Casas de Reina, a small town near Llerena, in the south of the province of Badajoz. In ancient times it was in the province of Baetica, attached to the conventus Cordubensis.
Neither the mining wealth of the area, nor its important strategic location, an important pass towards the Vegas del Guadiana, went unnoticed by the Romans. After the first skirmishes with the indigenous tribes and, above all, with the Lusitanian bands, the Romans erected a first settlement to control the territory at Cerro de las Nieves. With the pax Augusta, as happened in other towns, the high ground was abandoned and the city was built on the plain.
A city devoted to mining, it exercised administrative control over a large territory. As a result of this prosperous activity, in the time of Vespasian, it was granted the legal status of municipium.
