Château de Colombey

The Château de Colombey, located in Coincy in Moselle, was a castle of the former commune of Colombey, built by Baron de Tschudi in the 18th century. It was burned during the Franco-Prussian War of 1870 and completely demolished after the First World War.
History+
In the tenth century, Colombey was a collection of huts serving as dwellings for serfs, with a castle at its center flanked by turrets with arched windows, thick walls studded with loopholes. One of the turrets was topped with a metal pigeon, the dovecote. Another ended with an iron cross, which was the castle chapel, later to become Saint-Nabor church. The highest tower, remarkable for its full-arch entrance and its jagged armorial escutcheons serving as a weather vane, constituted the keep. In 1681, the old feudal castle was still standing at the end of the village, on the church side, with its four-pillar dovecote, a sign of high justice, and its enclosure of towers. In the 18th century, Théodore de Tschudi had the old feudal castle demolished to build a large house in the style of the era: less imposing but more pleasant to live in and more comfortable, opening onto a garden. He began to develop the small wood into a park where Lorraine species grew: beeches, oaks, and hornbeams. His son converted the surroundings of the castle into an English park. He had trees from Asia, Africa, and America planted at great expense and allowed his contemporaries in the vicinity of Metz to discover the black locust, acacia, sophora, American walnut, and Japanese lacquer tree. The castle, taken and retaken during the clashes of the 1870 war, was set on fire on September 27, 1870; the park, gardens, and nurseries were devastated. It was completely burned by order of the Metz garrison on October 27 of the same year. Here is the description given by Charles Abel, president of the Metz Academy, visiting Colombey after the battle: "I was eager to see what petroleum had spared in this residence, which evokes dear memories among our scholars and horticulturists. But I remained completely bewildered, searching for those beautiful farms, that remarkable greenhouse where so many experiments had been carried out under the auspices of the Metz Academy. I saw only walls blackened by petroleum smoke. Where I had admired rose beds and groves of exotic trees, twenty graves of German soldiers stood in place of flowerbeds." A painter, J. B.
