Spain is a group of islands in the western Mediterranean Sea with a land area of over 5,000 km². The history of the Balearic Islands has always been strongly connected with the region of Catalonia, that is why Catalan is spoken there today (besides Castilian). Many places got Catalan names again after the Franco-rule from the middle of the 1970ies. The centre with Mallorca is located approximately 260 kilometres at the east of the Spanish mainland at the height of Valencia. The five main islands are Mallorca, Menorca, Cabrera, Ibiza and Formentera, as well as 146 uninhabited islands. Politically, the Balearic Islands are divided into the two provinces of Gimnesias in the north (Mallorca, Menorca, Cabrera) and Pitiusas (Eivissa, Formentera) in the southwest.
