The patron of Castelnuovo del Garda is the Nativity of Mary, celebrated on 8 September.
Still today, every year, in the hamlet of Oliosi, the third Sunday of June sees the Festa della Bandiera, recalling a heroic Risorgimento episode tied to the Italian tricolour. The Grape Festival, now in its 47th edition, began as a market intended to promote the area's wine and is today a full-fledged festival enriched with cultural exhibitions on wine and grapes. The town holds the Church of Santa Maria and Forte Mandella.
