The patron of Agra is Saint Eusebius of Vercelli (sant'Eusebio di Vercelli), celebrated on 2 August; the municipality holds the Chiesa di Sant'Eusebio.
Every year Agra hosts two main sagre: the «festa del bambino» (children's festival), devoted to activities with a children's theme, and the «festa della zucca e della castagna» (pumpkin and chestnut festival), when the lanes and streets of the old town are set up as a market, mainly of products made from pumpkins and chestnuts.
