The municipality has no single centre: it stretches along the Arroscia valley and the climb to Colle di Nava, from 392 m at Ponti to 934 m at the pass. Every hamlet has its own history and its own festival.
The administrative centre of the municipality, home to the Town Hall and the main post office. It preserves the early-18th-century chapel of St Aloysius Gonzaga and the mid-16th-century chapel of St Anthony the Abbot.
Perched on a knoll overlooking the valley, Villa preserves its 13th-century castle and the parish church of San Dalmazzo. It is the heart of Ormeasco production, the ruby-red wine celebrated on the last Sunday of August.
The oldest and architecturally richest settlement in the municipality: medieval stone portals (one dated 1169), former artisan workshops and a still-working water system with oil mill, flour mill and sawmill. A 7th-century funerary urn was unearthed here around 1911. The San Bernardo Fair falls on the Sunday before 20 August.
An example of spontaneous rural architecture at 660 m. Here stand the 15th-century church of the Annunciation and the Baroque sanctuary of Madonna della Chiazza, frescoed in 1898.
A holiday resort on the pass linking Liguria and Piedmont. Five 19th-century forts, the Alpini memorial holding General Battisti's remains and a 15th-century Romanesque chapel. The Alpini Festival takes place on the first Sunday of July.
The most recent residential area, stretching along the SS28 road just below Colle di Nava. It is the starting point of hiking route G, the historical and monumental one.
