The Balearic Islands are an archipelago in the western Mediterranean Sea, near the eastern coast of the Iberian Peninsula. The four largest islands are (from largest to smallest): Majorca, Minorca, Ibiza, and Formentera. The archipelago forms an autonomous community and a province of Spain, of which the capital city is Palma. The co-official languages in the Balearic Islands are Spanish and Catalan (i.e. Mallorquí, Menorquí and Eivissenc, as Catalan is known by its speakers in this territory).
