Roman Catholic Diocese of Belfort-Montbéliard

Belfort Cathedral, otherwise the Cathedral of Saint Christopher of Belfort (French: Cathédrale Saint-Christophe de Belfort), is a Roman Catholic church located in Belfort, Territoire de Belfort, France. The cathedral has been a national monument since 1930. It was declared a minor basilica on 9 May 1952. The building that is now the cathedral was built as a church between 1727 and 1750 by the businessman Henri Schuller (or Shuler) (whose son was later a canon here) to plans by Jacques Philippe Mareschal, king's engineer at Strasbourg. It was built of red sandstone excavated from the quarry at Offemont, three kilometres from Belfort. Although the church opened for worship in 1750, the north tower was not completed until 1845. It contains an organ by the organ-builder Joseph Valtrin, installed in 1752 and now classed as an historic monument in its own right. On 3 November 1979 the Diocese of Belfort–Montbéliard was created from part of the territory of the Archdiocese of Besançon. The seat of the bishop was established at Belfort, and St. Christopher's Church was elevated to the status of cathedral.

The siege of Belfort (3 November 1870 – 18 February 1871) was a 103-day military assault and blockade of the city of Belfort, France by Prussian forces during the Franco-Prussian War. The French garrison held out until the January 1871 armistice between France and the German Empire obligated French forces to abandon the stronghold in February 1871. Belfort is located in a gap between the mountainous southern Vosges and the Jura Massif, strategically positioned as the gateway between Alsace and central France. At the beginning of the war, the French Army of the Rhine was routed in northern Alsace. The fall of Strasbourg on 28 September 1870 allowed the German army under August von Werder to move south against Belfort. Upon hearing of the approaching German army, Pierre Philippe Denfert-Rochereau, commander of Belfort, began constructing fortifications around the city, expanding those originally built by Vauban. Werder's forces reached Belfort and invested the city on 3 November. The intransigent resistance by the French forces stopped the Germans from completing an effective encirclement of the city. General Charles Denis Bourbaki assembled an army intending to relieve Belfort. On 15 January 1871 Bourbaki attacked Werder along the Lisaine River; however after a three-day battle he was repelled and his army retreated into Switzerland. German forces grew impatient with the length of the siege and on 27 January 1871, General von Tresckow launched an attack on the city which was repulsed and the siege operations resumed. On 15 February an armistice was signed between France and Germany. Louis Adolphe Thiers, president of the Government of National Defense sent an urgent message to Denfert-Rochereau ordering him to surrender the fortress. On 18 February the Belfort garrison marched out of the city with the honours of war, taking their weapons and baggage train with them. In recognition of the French defense of Belfort, under the terms of the Treaty of Frankfurt, the city and its surrounding area were not handed over to Germany, unlike the remainder of Alsace. In 1880, the monumental Lion of Belfort sculpture was inaugurated in tribute to the defenders of the city.

The Lion of Belfort, in Belfort, France, is an 1880 monumental sculpture by Frédéric Auguste Bartholdi, the sculptor of the Statue of Liberty (Liberty Enlightening the World).

Fort des Basses Perches, also known as Fort Valmy, was built between 1874 and 1877 in Danjoutin and Belfort in northeastern France. It is part of the first ring of fortifications around the city of Belfort. The Forts des Perches were unique among the first group in their re-use of older sites. They were rebuilt as part of the Séré de Rivières system and incorporated improvements to deal with the improvement in efficacy of artillery in the late 19th century. The fort's official name was derived from François-Christophe Kellermann, Duke of Valmy and Marshal of France. The first fortification at the Perches hill was an excavated rampart dating to 1815. A dry-masonry fort was built at the Basses Perches location in 1870 by Colonel Pierre Denfert-Rochereau during his defense of Belfort, at an elevation of 425 m. The present Fort des Basses Perches was built on this site, as it had proven to be a strategically important part of the southern defenses of Belfort during the Franco-Prussian War. The roughly rectangular fort is notable for its early use of counterscarps in place of caponiers, which had been more popular until then. The Fort des Basses Perches is small compared to others in the Belfort defensive array. It accommodated 126 soldiers, 4 non-commissioned officers, and 2 officers. Initial cost was 939,000 francs d'or. It was initially armed with 4 155mm long guns, 9 138mm guns, 4 121mm guns, 1 22mm howitzer and 2 22mm mortars. From 1893 the fort was linked to other forts around Belfort via the Chemins de fer du Territoire de Belfort strategic railroad. The Fort des Hautes Perches is about one km to the northeast. Apart from a concrete observation post built between 1914 and 1918, the fort was never modernised. It is now owned by the commune of Danjoutin and is open to the public by appointment.
