Traces of this castle can be found in the archives dating back to 1315, when it was under the jurisdiction of the lord of Saint Geoirs. A remarkably well-preserved tower still remains.

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."

In 1869, the Marist Brothers purchased the castle and its grounds. They raised the body of the central building by one floor. The castle was then acquired by the city in 1906. In 1914, it became a military hospital and from 1940 to 1960, a modern college. The castle now houses a music school and meeting rooms. Many areas are vacant. The Ministry and the public agency for cultural cooperation (aida) conducted a feasibility study for the establishment of a European Cultural Exchange Center in the building. If you take a walk in the park in the afternoon, you can hear the musicians practicing.
