Église Saint-Crépin de Château-Thierry, Gothic church in Château-Thierry, France.

Église Saint-Crépin is a hall church in late Gothic style, rebuilt between 1487 and 1520. Its pale grey stone facade has a gabled section with a round clock, a pointed traceried window and a stone balustrade above a deep pointed archway with red double doors. A tall square tower with vertical buttresses and louvered openings rises on the right.

The building was first mentioned in a papal bull in 1155 and received its current form during reconstruction between 1487 and 1520 after damage from the Hundred Years War. This rebuilding shaped its architectural character significantly.

The 16th-century organ balustrade carries 19 statuettes in shell-topped niches: virtues such as Faith with a cross, Fortitude with a broken column, Justice with sword and scales, and pagan sibyls holding a manger, a rose, a lantern or a crown of thorns. Theologians held that the sibyls had foretold a messiah, which admitted them into sacred art.

The church welcomes visitors during daylight hours alongside regular worship activities. Access may be limited during religious services, so visiting outside service times offers better opportunity to explore.

The church keeps a 15th-century organ loft whose 16th-century balustrade carries 19 statuettes of virtues and pagan sibyls, including the Samian sibyl holding a crib and the Erythraean with a rose. The same sibyls with the same attributes appear at Beauvais Cathedral.
