Castelbianco is a tiny commune in the lower Pennavaire valley, made up of the hamlets of Colletta, Oresine, Veravo (the municipal seat), and the ruins of Vesallo, which was destroyed by an earthquake in 1887 and never rebuilt. The area was once a possession of the Cepolla family of Albenga before passing to the marquisate of Zuccarello in 1383, then to the Savoy, and finally to the Republic of Genoa.
The village houses have a characteristically Ligurian appearance — stone walls with windows framed by white borders. Colletta di Castelbianco, perched on a hilltop, has been carefully restored as a "tele-village" with satellite internet in every house, attracting remote workers and artists to what was once an abandoned medieval hamlet.
The baroque parish church of the Assunta at Veravo and the church of the Annunziata at Vesallo (the latter with two campaniles, one tall with an onion-shaped spire) are worth a look if you pass through. Ruins of the medieval castle include substantial sections of wall. The commune shares the agricultural character of the nearby Albenga plain, producing cherries, vegetables, and olives.
