Calvinist Temple of Cosswiller
Cosswiller, once connected to the vanished villages of Romanswiller and Dann during the Thirty Years' War, was rebuilt and became a place of Reformed Protestant worship. Its temple, built in 1819, is notable for its understated architecture: it was designed to resemble a house rather than a religious building. Some parts come from the Marmoutier library and date back to the second half of the 18th century, such as the window frames and some door panels. The bell tower was erected in 1843. This temple replaces an older 12th-13th century building of which only the gate tower remained in ruins by 1820, though its exact location is unknown. The current building has a rectangular plan, with two levels of side windows and five bays. Inside, the space is ceilinged, and the small bell tower, positioned above the front facade, rests on columns.
