Église Saint-Germain d'Andrésy, Gothic church in Andrésy, France.

The Saint-Germain Church displays Gothic architecture with a central nave flanked by unequal side aisles, ribbed vaults, and large pointed arch windows that illuminate the interior with natural light filtering through ancient stained glass windows.

Built primarily between the late 12th and early 13th centuries, the church underwent major modifications during the 16th century under François I, including the reconstruction of the south side aisle and the addition of a wider north collateral in Renaissance style.

The parish is dedicated to Saint Germain of Paris, and the chapter of Paris held the right to appoint its priest. Since the Revolution it has belonged to the diocese of Versailles, together with Maurecourt, which was only then detached from Andrésy as a separate parish. Sunday masses are still held here every week.

Located at 14 boulevard Noël Marc in Andrésy, the church remains active for Sunday masses and religious ceremonies, though visitors should verify opening hours as restoration work and liturgical activities may affect accessibility.

Eleven capitals in the church date from the second half of the 16th century and carry carved figures: bearded men, winged female busts, eagles and sirens. Two of them show fire salamanders, the emblem of King Francis I, a detail easily missed at the top of the columns.
