Returning to Cantalupo, on the right, turning along the Attone stream and you can climb to Castelbuono.
Probably the first settlement dates to the end of the 10th century and the castrum had defensive purposes.
Today you can see the remains of a very suggestive castle that in the Middle Ages constituted, together with Limigiano, the defence of Bevagna from Todi, on the north-western side. What remains of the ring of walls testifies the history of this free Municipality, which had its own statute in 1345, published in 2004 by the Comprehensive Institute of Bevagna, within the Montagna Project, and with the contribution of Pro Loco Cantalupo-Castelbuono.
Castelbuono appears in the first documentary sources with the name Castrum Abbonis or Abboni (Castellum Aboni), perhaps of anthrophonic derivation.
It is remarkable that today in Italy there is only one Municipality with the same name: Castelbuono, in the province of Palermo.
Santa Maria is the only remaining church of the five existing. It has a curious polygonal bell tower with two pointed arches at the base. Inside, among others, on the left of the main altar you can see in a a Holy Temple a fresco by Ascensidonio Spacca, known as Il Fantino, representing the Madonna with the Child, San Giuseppe and San Giovanni the Evangelist; on the right the Madonna della Misericordia and the Mysteries of the Rosary by Anonymous of the 16th century, with San Domenico added by the same painter.
Along the walls there are decorated little chapels.
A fragment of a travertine double-sloping cinerary urn cover id Inserted in the corner of a house-wall, inside the village.
Frontally you can notice a togated half-bust figure, the inscription is lengthened on a single line along the base bar of the lid: Cn(aeus) Salvenus. The gens Salvena is documented by two other inscriptions always engraved on lid of cinerary urns coming perhaps from Torre del Colle, not far from Castelbuono, and therefore perhaps of the same tomb complex.
