The first castle of Châteaugiron was built in the middle of the 11th century by Anquetil, a Norman knight, who had received the lands from Alan III, Duke of Brittany. The oldest part of the current castle is the castle's Romanesque chapel dating from the 12th century. Probably in the 13th century, Châteaugiron castle was rebuilt as a stone fortress. Currently the Château de Châteaugiron fulfills several functions; its main body is used as a town hall, the other parts are used as offices and the independent keep is used for exhibitions.

This church stands in the middle of the countryside, you can see it from afar, it is magnificent! The bell tower in the form of a "bulb", characteristic of the Byzantine style, made it pass for an Orthodox church, while it is just linked to the originality of the architect in 1875. Anecdote of the German occupation: in 1941, the Nazi propaganda filmed a film there ("Threshing wheat in Ukraine") to make believe in an advance of German troops in Ukraine (against the Soviet Union). Until 2011, the church was under the patronage of St. Peter the Apostle. On this date, his patronage was changed to that of Saint-Maximilien-Kolbé (1894-1941), a Polish priest with exceptional charisma, especially in the face of Nazism. Held in the Auschwitz concentration camp, he offered himself to take the place of a father sentenced to death. He was canonized (recognized as a "saint" by the Catholic Church in Rome) in 1982.
