Cornello’s church stands at the highest point of the village and is characterised by a Romanesque tall and slightly leaning bell tower.
The church, as it appears today, is almost certainly the result of the transformation of an earlier 12th and 13th-century building, of which very few traces remain.
The gabled facade has a wide stone doorway with a pointed arch while the interior has a nave, divided into three bays characterised by lots of frescoes.
The vast cycle of frescoes dates back to the period between the 14th and 16th cent. and present a variety of themes and a remarkable stylistic taste: there are some figures with the typical clothing and bearing of common folk and more sophisticated subjects, who are depicted in contemplative poses and in splendid garments.
The creation and management of this church was linked to the Tasso family who financially supported it.
