The patron of Nomaglio is San Bartolomeo, celebrated on 24 August; the municipality holds the Chiesa di San Bartolomeo.
Chestnut groves are joined, going down toward the valley floor, by coppice woods, pastures and orchards: the Nomaglio cheeses produced on these pastures, though in small quantities, were once famous. The municipality also holds the Ecomuseo della Castagna and the Chiesa di San Grato.
