The municipality of Giron was created in 1790, however its borders were only set much later in 1815. Before, the municipality was divided into two separate entities: “Giron-devant” which belonged to Champfromier, and “Giron-derrière” belonging to Échallon. The neo-classical style church was built in 1840 in Giron-Devant, in the most recent area of the village. Restored in 1902, it is also a symbol of the municipality’s religious and administrative.
