Following the Regional Law, after the election in 2005, a new territorial repartition has been made, with an increase of the provinces from two to four.
Sassari, the biggest province notwithstanding the separation of “Gallura”, is situated in the North part of the island and it is delimited by a variegated coast, sometimes plain, sometimes made of rocks, sometimes open on gulfs like the “Asinara” one.
For what concerns towns, Sassari, with its ancient part, full of narrow and tortuous streets, Porto Torres, the ancient Roman Turris Libysonis, now important tourist and commercial harbour. Alghero, founded by the Genoese as a fortified towns to protect the inhabitants from the Saracen attacks, and then passed to the Aragonese after a memorable siege. In their dialect, which is very similar to Catalan, you can find the traces of this occupation. Remarkable Castelsardo, a picturesque town on a promontory facing the sea.
