This Renaissance structure was constructed by Mansart between 1632 and 1634 under the direction of François de Sales and Jeanne de Chantal.  Originally, it was the old Marais parish church known as the Saint-Marie Temple.  Spared during the Revolution, it was converted into a Protestant church in 1802.  It has a variety of Protestant Sunday services in French, Japanese, Arabic, and a service labeled Afro-Carribbean.

When I took this photo, it was for the large doors of red, but in reading about this church I feel compelled to return when it is open.  There are tours one Sunday each month.

Bon dimanche
