The patron saints of Muggiò are Saints Peter and Paul and Our Lady of Sorrows of the Chestnut, celebrated on the third Sunday of September.
On 16 August, for the feast of Saint Roch, a procession sets out from the chapel dedicated to him towards the parish church of Santi Pietro e Paolo Apostoli. The municipal territory also holds two stone columns topped by an iron cross, known as the Plague Crosses, as well as Palazzo Taccona and Villa Casati.
