The patrons of Nibionno are Saints Gervasius and Protasius, celebrated on 19 June in the Church of Santi Gervaso e Protaso.
Every year, between May and June, in the Molino Nuovo area, a feast is held, animated by the theatre company «il Portico degli Amici», the «Giuseppe Verdi» band, and the «don Olimpio Moneta» choir. The town also holds the Torre di Tabiago and borders the Lambro Valley Park.
