This church is, as you probably know, the oldest in Paris. It was founded by Childebert, son of Clovis, the first king of France and is dedicated to the saintly Germain who was Bishop of Paris in Childebert’s life. It is located in what, at the time, were flood-prone fields as the “Prés” indicates, being the French word for fields.
This is the church where the remains of Rene Descartes were moved from Stockholm but, as near as I can tell, there is little, if anything, here. There is what looks like a marble memorial to him between two chapels. It praises his intellect and his contribution to the literature and thought of his time. Some regard him as the father of the enlightenment.
The church was built, as so many were, to house and honor a holy relic, in this case the stole of St. Vincent, brought from Spain by Childebert in the 6th Century. The abbey became one of the richest in France and a Catholic intellectual center until the French Revolution. There is a lot of interesting statuary and paintings to be seen, one statue of St. Germain and a 13th Century one of the Virgin and Child which has been pieced back together from three stone pieces found in a recent archeological dig nearby.
In St. Germain visit the daily (except Monday) food market stalls on Rue de Buci. Wander around have a crepe, shop, find a cafe, have a beverage, repeat.
