Église Saint-Hilaire de Nogent-le-Rotrou, Church and historical monument in Nogent-le-Rotrou, France

Église Saint-Hilaire is a stone church in Nogent-le-Rotrou, in Eure-et-Loir, listed as a historical monument in 2003. Its steep brown-tiled roof covers a long nave and a lower side aisle; the left facade has a pointed-arch window with tracery above a dark rectangular door, and the lower aisle wall has round-arched windows with slender columns. A lighter square bell tower with arched openings, a clock face and a domed cupola with lantern and cross stands at the right.

The oldest part of the church dates to the 11th century, while the choir was rebuilt in the 13th century. The nave, tower, and bell tower were added in the 16th century, giving the building its current form.

The church bears the name of Hilary, bishop of Poitiers in the 4th century. Its glazing spans more than a century: fourteen windows were made and installed by the Lorin workshops of Chartres in the 19th century, others date from 1866 and were supplied by Le Dien of Argentan, and Bernard Campin of Chartres produced further windows in 1947.

The church stands on Avenue du Maréchal-Foch in the center of Nogent-le-Rotrou and is easy to reach on foot. Visiting outside of Mass times allows you to explore the interior without interruption.

The church has an organ built in 1876 by Georges Wenner, with around 700 pipes, that fell out of use for many years. After a long closure, the building reopened in 2013 following restoration work on the organ and the stained glass windows.
