Fleix Protestant Church dates from the Reformation and the official recognition of the creed in 1587.
Fleix’s first Protestant church was situated at the village entrance ; it still existed in 1679 but was probably demolished after the revocation of the Nantes Edict.

The main pavilion of Fleix castle subsequently became the Protestant church, replacing the one which still stood in the seventeenth century.

The church was consecrated in July 1801; restoration work was carried out in 1898-1899 and the inauguration of the newly renovated church took place on 9 May 1899.
