The western group, corresponding with the ancient Pityusae or Pine Islands, also comprises two relatively large islands, Iviza (Spanish, Ibiza or, formerly, Ivica) and Formentera, with the islets of Ahorcados, Conejera, Pou and Espalmador.
Majorca, Minorca and Iviza are described in separate articles.
The direction of the folds in the older series is in Iviza nearly west to east, in Majorca south-west to north-east, and in Minorca south to north, thus forming an arc convex towards the south-east.
There are five judicial districts (partidos judiciales), named after their chief towns - Inca, Iviza, Manacor, Palma and Port Mahon.
Formentera is described with Iviza.
