This is the second-largest island in the Mediterranean. Much of Sardinia away from the coasts is an almost lunar landscape of crags and chasms and is largely uninhabited. The coastline is jagged and rocky, interspersed with marvellous beaches of very fine sand. In recent years there has been much investment in tourist infrastructure, particularly in the northern area known as the Costa Smeralda (Emerald Coast), which has become a favourite retreat of Italian celebrities, and on the west coast near Alghero. This is the only region in Italy without motorways. The Sardinian language is closer to Latin than is modern Italian.
