evidence: Ceuta is a 7-square-mile chunk of Spain attached to Africa — a peninsula that juts out from Morocco into the turquoise Mediterranean Sea. It's one of two Spanish cities, along with Melilla, that are part of the European Union but physically part of Africa. [...] Morocco has asked for control of Ceuta. It considers the peninsula part of its own territorial integrity. But Ceuta's people themselves — both those of European and Moroccan descent — overwhelmingly want to remain part of Spain. [...] This year, Ceuta marks 600 years as a European territory. It has the potential to change stereotypes of what it means to be European, Muslim or African — or paradoxically, all three. But Spain will have to deal with issues of inequality and security, if it wants to keep Ceuta for centuries to come.
