There are countries in North Africa and West Africa that were colonized or partially colonized by the Spanish, where Spanish still has some official or semi-official status and or is still popular as a second language (you can find a list and relevant articles on Wikipedia). There are also Ceuta and Melilla, two tiny Spanish colonies surrounded by Morocco. The Canary Islands, off the Coast of Africa, belong to Spain. Generally, however, Portuguese is the most famous Iberian Romance language in Africa, especially southern Africa. Of course, with the internet, anybody anywhere can study any language they want. Do you have something specific in mind?
