Saint-Eustache Church is the second largest church in Paris after Notre-Dame, and it is actually taller! Building spanned centuries starting in 1530, hence a mix of a Gothic structure, Renaissance decoration and an eighteen century classical architecture facade.
You will be astonished by the organ, made up of eight thousands pipes, it is the largest one in France.
The great playwright Molière was baptized in Saint-Eustache, the Requiem mass for poet Jean de la Fontaine took place there and composers Berlioz and Liszt performed in the church.
Contemporary art is rather rare in French churches, but in Saint-Eustache, you will come across a bronze triptych by Keith Haring, one of his last works before he passed away.
