Fontaine Sainte Radegonde, Chapel-fountain in La Châtre, France

The chapelle-fontaine Sainte-Radegonde, also known as la Grand Font, is a 15th-century chapel-fountain in La Châtre, France, listed as a historical monument. It is built on a six-sided base with three niches: two serving as chapels and one giving access to the water source.

Built in the 15th century at the foot of the old keep of La Châtre, this small edifice is a rare surviving example of a public fountain from that period. It was restored in 1853 and inscribed as a monument historique on 16 July 1925.

The name honours Radegonde of Poitiers, a Thuringian princess born around 519 who became queen of the Franks by marrying Clotaire I. At La Châtre, pregnant women came to this chapel to seek a safe pregnancy, and one niche holds a statue of the saint.

The chapel-fountain stands at the foot of the former keep of La Châtre, in the Boischaut Sud area south of the Indre department. It is a small open structure reached on foot from the surrounding streets; the iron gate and the niches are seen from outside. Look for the trefoil-pierced round window and the two corner pinnacles.

The top of the base was once crowned with a calvary, which has since disappeared. Some of the gables are still decorated with curly-kale finials, a very specific Gothic ornamental motif from the 15th century.
