Imperia is the provincial capital of the western Ligurian Riviera, formed in 1923 by merging two older towns — Oneglia to the east and Porto Maurizio to the west — separated by the Imperia river. The two halves retain distinct characters: Oneglia is the commercial and port side, known for olive oil production and pasta; Porto Maurizio is the historic town, perched on a promontory with a medieval centre, baroque cathedral, and views over the Ligurian Sea.
The town is less visited than the Cinque Terre or Sanremo and is the better for it. Porto Maurizio's old quarter — the Parasio — is pleasant to explore on foot, with narrow caruggi lanes leading up to the Cattedrale di San Maurizio and a belvedere overlooking the coast. In Oneglia, the Museo dell'Olivo covers the history of olive cultivation with unusual depth. The surrounding area produces some of the best olive oil in Italy — the DOP Riviera Ligure designation applies here. The Lungomare connects both halves of the town along the coast, and Calata Cuneo at the Oneglia port is where to eat.
