It certainly could be a settlement connected to the lost Iberian civilization of Tartessos, which did exist, @1200BC-700BC. This merged, it seems, with that of Phoenician settlement in the area. That whole region has rather mysterious ruins and artifacts.
The city of Tartessos itself has not really been identified, in spite of several definite mentions in ancient literature. Some say it is near Huelva, where there are visible ruins, some say it was drowned in the marshland of the Coto Donana, etc. Related settlements elsewhere have been tentatively identified.
Its curious how a civilization noted for trade, and moreover a literate one, with its own writing system, has so completely disappeared. Its probably the Tarshish mentioned in the Bible.
Anyway, artifacts labelled as Tartessian are in many Spanish museums, and I’ve been to lots. There is a good display in, of all places, Alcala de Henares. The one in Cadiz is certainly worth a visit.
One of many “Tartessian” artifacts - this one is in the Archaeological Museum in Madrid. Several similar ones are in Cadiz.

This again? There are always “Lost Cities” being found and lost again. I remember well the cities discovered off the coast of Chile, South America back in Feb 1966. Newspapers all carried stories of it. Haven’t heard a word about them since.
Everyone knows that Atlantis is in the Pegasus galaxy.
There is even a documentary series about it.....
