A scattered municipality situated in the valley of the Neva in the Ligurian Alps, it grew up on the ancient Salt Road. A possession of the marchesi di Clavesana since the twelfth century, it was sold to the Savoy in 1623. Subsequently acquired by the republic of Genoa, it shared its fortunes. It was sacked by Napoleon’s troops in 1796. The parish church of Santa Caterina, opposite the oratory of San Giovanni and flanked by a campanile built in the late Middle Ages, is a simple building of the baroque era. The parish church of San Martino di Erli, from the eleventh century, houses fifteenth-century frescoes. The extremely well-preserved Borgo dei Bassi, on an elliptical plan, is a significant example of a medieval settlement. The agriculture is typical of the mountains. There are extensive chestnut woods where mushrooms are collected.
