The patron saint of Arcore is Saint Eustorgius, celebrated on the third Monday of September in the Church of Sant'Eustorgio.
On the first Sunday of October, the Regina del Rosario parish community celebrates its own patronal feast, accompanied by the traditional town fair. Since 2003, the town has also hosted the Arcore Street Festival, an artistic-cultural event involving artists, musicians, jugglers and street performers throughout the historic centre. The municipal territory also holds Villa Borromeo d'Adda and Villa San Martino.
