After having fortified, around 1245, the summit of the hill of Hombourg with an imposing castle, the bishop of Metz Jacques de Lorraine founded in this place, in 1254, a chapter of canons, for which he ordered the construction of a large and beautiful church dedicated to Saint-Etienne and the Virgin. The church occupies a commanding position at the top of the rocky promontory, from where it is visible from almost all sides. Sensibly oriented East-West, it is located in the extension of the town which developed at its feet. In a Gothic style from the 13th and 14th centuries (it was started at the end of the 1400th century and completed around 1632), the church has a fairly massive and squat appearance. The building is built of pink-ochre sandstone with a beautiful regular structure, except for the north transept which is covered with a coating. It burned in 1789 but escaped the ravages of the Thirty Years' War and the Revolution of 1930. Symbol of the city, the church was classified as a Historic Monument in XNUMX.
