Popular around Bilieu
Medieval origins (11th - 12th centuries): The religious site is of very ancient origin. From the end of the 11th century, several religious buildings are mentioned in the commune. The Saint-Pierre church itself is cited under the name "ecclesia de Anos" in the famous cartulary of Saint Hugues (Bishop of Grenoble). In the Middle Ages, the church was directly dependent on the priory of Saint-Laurent of Grenoble, as attested by an official terrier dating from 1497 under the name "ecclesia Sancti Petri de Fortaressia".

The feudal castle of Tullins, located in Isère, today consists of the ruins of an ancient 12th-century fortress overlooking the old town. Built in the 12th century as a stronghold of the princes of the Dauphiné. Several families succeeded each other at its head, then it was leased in 1428 by the future king Louis XI. The de Clermont-Tonnerre family obtained it in perpetuity in 1650. A fire ravaged the site in 1740. A round tower from the 12th century (with openings and windows modified in the 15th and 16th centuries) remains, as well as fragments of walls.

During Holy Week, Christians commemorate the Passion of Jesus Christ, beginning with the triumphal entry into Jerusalem (Palm Sunday), the Last Supper (Maundy Thursday), and ending with the arrest, condemnation, and execution (Good Friday), which then culminates in the Easter Vigil with the celebration of the Resurrection, the climax of the church year. The biblical accounts of the New Testament that describe these events paint a very nuanced picture of the Apostle Peter (Saint-Pierre), to whom the church of Charavines is dedicated: on the one hand, he is a determined disciple of Jesus, but also not free from human weakness and fear. In the Garden of Gethsemane, he (like the other disciples) falls asleep when Jesus turns to God the Father after the Last Supper and asks the disciples to pray as well. And after Jesus' arrest, Peter denies three times that he even knows him. But he also weeps over his weakness and, upon encountering the risen Christ, affirms his love and loyalty to him. His real name is Simon, but Jesus gives him the name Peter (which means "rock") on which the church is to be built and gives him—according to the account of the Evangelist Matthew—the "keys to the kingdom of heaven."
