Originally dedicated to the Blessed Virgin Mary, the church has been named after Saint George since 1500 and is famous for its Christmas trees hung since 1521[4] The building was first mentioned in records from the eighth century and was originally a baptismal chapel in the imperial palace built by Charlemagne, which the emperor is believed to have visited at Christmas in the year 775.

Building of the new church — on a Latin cross groundplan with three aisles and a transept — started around 1220 and continued without interruption until the early fifteenth century.

The construction of the tower continued during the fifteenth century and a rood screen was built in 1489 and 1490 by Conrad Sifer, but was destroyed during the French Revolution.

A relief carved on the reverse is the veil of Saint Veronica, showing nails and the Holy Face.

A staircase mounting the height of the nave bears the date 1615, the name of "Stéphane Exstel" and a stonecutter's mark.

The Adoration of the Magi is represented on the tympanum, and oak leaves and vines are carved on the capitals of the columns.

The tympanum, with round arches, is adorned with a carved decoration in bas-relief featuring oak leaves and vines.

Its tympanum is broken, and the splayed arch is decorated with sculptures, replacing those destroyed during the Revolution, by Sichler in 1847.

The keystones in the church, carved from sandstone and painted in full colour, date from the thirteenth to the fifteenth century.

Their paintwork was restored in 1859 by Antoine François Denecken to their original state, i.e. in red and blue with gold detail.

The individual keystones are decorated with various Christian symbols: the tetramorph, Christ, the Lamb, foliage, oak leaves and vines, Saint John the Baptist, Saint Agnes, a peasant, the Coronation of the Virgin, the Risen Christ and a king and a sword.

The grey sandstone altar has statues representing King David playing his harp and the sacrifice of Isaac.

The original organ by Johann Andreas Silbermann was moved to the Dominican church in Colmar in 1896.

Although they date from the fifteenth century, they are substantially the work of Théophile Klem, who had them restored in 1862 at a cost of 3,000 francs.

An engraved silver ciborium dating to the fourth quarter of the eighteenth century is preserved in the church.

It was classified as a historical object on 5 August 1994, restored in 1996 (though not to its original condition), and is currently displayed in the Sélestat tourist office.
