The church of St. Michael the Archangel stands in an elevated position above the village of Badia Tedalda. The organism of the church is simple: irregular wall face and a gabled roof covering the single nave. Inside there is a surprise in coming across various altars all in glazed terracotta referable to the Della Robbia or direct followers, particularly Santi Buglioni. Restoration of the two altarpieces in the nave was necessary to remedy the disintegration of the plaster additions to the altarpieces. In view of the special microclimatic condition of the church, with high humidity, we opted for a slightly differentiated integration in terms of chromatic appearance but using the same technique of glazed terracotta.
