It is the most north-western town in Andalusia, bordering Extremadura and Portugal. The holm oak, together with the cork oak -and later the oak-, is the characteristic tree of the area and of practically the whole of this western strip of Spain.
According to some legends, the name comes from a solitary tree under which the border smugglers used to gather; but, although smuggling activity has been present for a long time and until recently in these lands, and there is evidence of this in the toponymy itself –Cuesta del Contrabandista– and perhaps even in the gentilicio itself –marocho-, the imposition of the name Encinasola must be older, so it cannot refer to smuggling. For a more extensive explanation of this toponym, as well as of the neighbouring Portuguese name Barrancos and the minor toponyms in the surrounding area, see García Sánchez (2023).
