Église Saint-Cyr d'Issoudun, Gothic religious edifice in Issoudun, France.

Église Saint-Cyr is a Gothic church in Issoudun built with six bays from the 14th century and crowned by a flat chevet at the altar end. The structure shows the typical proportions and vertical lines that mark Gothic church design.

After suffering fires and destruction by English forces in 1354, the church was rebuilt between 1354 and 1400 with its six original bays preserved. This reconstruction period shaped the structure that stands today.

The axial window of the choir, installed around 1470, marks the completion of the Gothic choir and shows the life of Saint Cyr in thirty compartments. Broken by a storm in 1810, it was reassembled and restored in 1937, boxed up in 1939 to protect it from bombs, and returned after the war. The other eighteen windows, from the second half of the 19th century, come from the Lucien-Léopold Lobin workshop in Tours, finished after 1892 by Joseph-Prosper Florence.

The church sits on Rue de la Republique in central Issoudun and is easy to reach on foot. As an active place of worship, visiting outside service times may require checking with local authorities beforehand.

The 16th-century stoup by the entrance is carved with shells. In the choir, the bench of the "maistres boulangers" (master bakers) is dated 1738, while another carries the inscription I. GAVDIN 1687 ROBER. and a third reads E DUTEIL 1732.
