Yes, the Phoenicians began arriving in small numbers to Iberia in the 9th (or more probably) 8th century BCE. They established what seem to have been small "trading" enclaves, or emporia, especially along the Costa del Sol / Andalusia. There are several sites, such as those at Toscanos or Morro de Mezquitilla. The enclaves tend to be at the coast, typically at the mouth of a waterway (good harbor) or on a small island some distance off-shore. They are active from about 750 to about 680 (roughly the Late Geometric period back in mainland Greece and the first horizon of Greek westward expansion as well), when nearly all of them are abandoned. The evidence suggests that the Phoenicians were there to interact and "trade" with the native Celt-Iberians. I say "trade" because these were likely not commercial transactions, but instead unequal exchanges of reciprocity between the Phoenician agents and the local elite. The Phoenicians were seeking raw materials, especially metals, from the resource-rich interior of Iberia. They offered in exchange exotic finished goods, like red-slip ceramic and Greek fineware, jewelry, Egyptian faience, et cetera.

These sites were essentially unknown until the 1960s, when there was a sort of Renaissance of scholarship on the Phoenicians. Before that time, they had always taken a very quiet back seat to Greek, Roman, Egyptian, Babylonian, etc. Since that time, through a lot of excavation, survey work, and pottery study, we have been able to establish relatively secure methods for dating material from these 8th-century Phoenician sites. Much of the work has been by German and Dutch teams.

The enclaves in Andalusia were in some way distinct and separate from larger Phoenician "settlments" in the area. The largest concentration of Phoenicians in Iberia at this time, we think, was at Gadir, modern Cadiz. Unfortunately virtually no archaeological investigation of this time period has happened at Cadiz, since there is a big modern city on top of the site. The site at Castillo de Dona Blanca might be associated with ancient Gadir, however, and is very near by.

Other large Phoenician "cities" of this time period were on Sardinia, on the western end of Sicily (at Motya), and of course at the tip of Tunisia at Carthage, the latter of which seemed to, at some point, take over as a sort of central hub of western Phoenician operations. When the Neo-Assyrians reconquered the Phoenician metropoleis back home, Carthage stepped into the role as the default hegemon, either militarily or economically or both, and developed as such from the sixth century on down to the period of their contact with the Romans and ultimate downfall.
