The fortifications of Paris in the 19th and 20th centuries comprise:

Contents

They were built in two stages:

From a military point of view, Paris is a fortified camp situated in a basin. During the 19th century, both Prussian invasions (1814–15 and 1870) saw the bombardment of Paris from the surrounding heights. Fortifications were extended outwards after each invasion as the range of artillery continued to develop, in order to deny the use of the heights to the enemy.

Chronology

Louis XIV

1670 The king demolishes the walls of Charles V and Louis XIII. Paris becomes an open city and remains so for two centuries.

1689 Vauban recommends the enclosure of Paris, with the construction of a second enclosure to include the then-villages of Chaillot, Montmartre and Belleville (located on heights overlooking the city), and two citadels flanking the city to the east and west to delay an enemy's approach.

Louis XVI

1784 The king orders the construction of the Farmers General Wall, built not as a fortification, but as a means of taxation.

Empire

1814-1815 Paris is occupied twice at the end of the reign of Napoleon I.

First fortification program

1818 Minister of War Laurent de Gouvion-Saint-Cyr creates a commission to "present its views on the best defense system" for Paris.

1820 The commission concludes that Paris must be placed in a state of defense, but proposes no specific project.

1830 Creation of a committee to study fortification which returns to the debate and again concludes that fortification is necessary, without consensus on how this is to be done.

1833 The defense plan for Paris envisages:

1836 Creation of a commission on the defense of the kingdom.

1838 On July 16 a plan of defense is adopted, combining the two options in a show of unanimity.

1840 The Convention of London and Near Eastern crisis raises the prospect of an anti-French alliance, and Adolphe Thiers seizes the occasion to commence the construction of the new fortifications. On September 1 General Guillaume Dode de la Brunerie is named director of the fortification program. The appointment and work is publicly announced on September 13.

1841 Over the reservations of the General Council of the Seine, 140 million francs are appropriated for the work, allocated, including 17,970 million francs for land acquisition, 16,608 million francs for earthwork, and 83,356 million francs for masonry. [1] The law authorizing work was promulgated by Louis-Philippe I on April 3, authorizing a continuous wall for both sides of the Seine, known as the Thiers Wall, supported by sixteen detached forts.

1845 Work is completed.

1860. The limits of the city of Paris are extended from the Farmers General Wall to the Thiers Wall, as part of the reorganization of the Paris urban fabric planned and executed by Georges-Eugène Haussmann.

Franco-Prussian War

July 1870 France declares war on Prussia, July 13.

September 1870 Napoleon III is captured at Sedan and capitulates. A republic is proclaimed and the Prussians move toward Paris. The capital is transformed into a fortified camp. A portion of the Thiers Wall gates are closed, along with canals and rail line entries. Houses are demolished in the designated "zone 'non aedificandi" to clear lines of fire. The Prussians arrive on 19 September and establish a siege, which will last four months.

January 1871 On the 28th the Treaty of Versailles is signed, stipulating that all of the forts forming the perimeter defense of Paris, together with their armaments, be handed over to the German forces. The treaty further stipulates the disarmament of the Thiers Wall.

March 1871 The German army abandons the forts on the left (south) bank of the Seine.

20 September 1871 The German army abandons the forts on the right (north) bank of the Seine. [2]

Second program of fortification

During the 1870 war, the fortifications were relatively ineffective.

1874 On 17 July, a law inspired by the ideas of Séré de Rivières creates new programs for defensive works in the north and east of France, including some intended for the defense of Paris.

1885. The program is completed. 196 forts, 58 smaller works and 278 batteries are in place on the borders and at strategic points within France at an estimated cost of 450 million francs for the works and 229 million francs for their armament.

The removal of the Thiers Wall

1883 On June 11 the municipal council of Paris votes to request the removal of the Thiers Wall, the property's transfer to the city and the end of restrictions on building in its vicinity.

1918 During World War I the Thiers Wall proves to be ineffective in the defense of Paris, as the range of German artillery such as the Paris Gun (120 km) renders walls irrelevant.

1919 On 19 April the city purchases the property for 100 million francs from the State of France. The city must purchase or expropriate the associated grounds and must maintain the "zone non aedificandi." Work begins on the demolition of the walls.

1925-1930 The "territoire zonier" is annexed to the city.

1930 A law is enacted to regulate the methods for compensation of the "zoniers."

The forts

Military doctrine for the employment of the forts

The doctrines for the use of the forts depend on the context of the time. During the 19th century the roads were few. Armies were obligated to move along existing lines of communication in order to maintain their provisioning without resorting to dirt roads in unfavorable seasons. Therefore, a fortification located on an important road would be able to slow or stop a large troop formation. For example the Fort de Charenton was placed to dominate Route Nationale 6, the Paris-Geneva road, and Route Nationale 19, the road to Belfort, as well as the fr:Pont de Charenton on the Marne and the fr:Pont à l’Anglais on the Seine.

In wartime, the fort would fulfill several functions, in the manner of a fortified town.

First ring of forts

Wall of the <i>Ferme générale</i> 18th-century city wall of Paris

The Wall of the Ferme générale was one of the several city walls of Paris built between the early Middle Ages and the mid 19th century. Built between 1784 and 1791, the 24 km wall crossed the districts of the Place de l'Étoile, Batignolles, Pigalle, Belleville, Nation, the Place d'Italie, Denfert-Rochereau, Montparnasse and the Trocadéro, roughly following the route now traced by line 2 and line 6 of the Paris Métro. The wall was demolished in the early 1860s, although elements of some of its gates remain.

<span class="mw-page-title-main">City walls of Paris</span>

The city walls of Paris refers to the city walls that surrounded Paris, France, as it grew from ancient times until the 20th century, built primarily to defend the city but also for administrative reasons. Several successive city walls were built over the centuries, either adding to existing walls or replacing demolished ones, through 1846, when construction of the Thiers wall was completed.

<span class="mw-page-title-main">Thiers wall</span> Former defensive wall in Paris

The Thiers wall was the last of the defensive walls of Paris. It was an enclosure constructed between 1841 and 1846 and was proposed by the French prime minister Adolphe Thiers but was actually implemented by his successor. The 33 kilometres (21 mi) long wall and ditch made a complete circuit around the city as it stood at the time of the July Monarchy. It was bombarded by the Prussian Army during the Franco-Prussian War, captured by government troops during the Paris Commune and refortified at the start of the First World War. However, by then it had become obsolete as a fortification and was a barrier to the expansion of the city. The area immediately outside of it, known as "the zone", had become a shanty town. The wall was demolished in the interwar period; its path today can be traced by the Boulevards of the Marshals which originally ran just behind the fortifications and by the Boulevard Périphérique which was later built just outside. A few remnants of the wall can still be seen.

<span class="mw-page-title-main">Fort de l'Est</span>

Fort de l'Est is a military strong point designed to protect Paris. It was built between 1841 and 1843 in Saint-Denis at the direction of French prime minister Adolphe Thiers, and was part of an immense defensive belt comprising 17 detached forts and the Thiers Wall surrounding Paris. The evolution of artillery quickly made these fortifications obsolete.

<span class="mw-page-title-main">Fort d'Ivry</span>

Fort d'Ivry was built in the Paris suburb of Ivry-sur-Seine between 1841 and 1845, as one of the forts in a ring of strong points surrounding Paris. The fort is about 1 kilometre outside the Thiers Wall, built by the same program in response to a perception that Paris was vulnerable to invasion and occupation. The fort was upgraded in the 1870s, to cope with improvements in artillery performance as part of the Séré de Rivières system. In 1946, the fort was vacated by the garrison. It is now the home of the Communication and Audiovisual Production Company for the Department of Defense.

<span class="mw-page-title-main">Fort de Villiers</span> 19th c. French fort near Paris

Fort de Villers was built following the Franco-Prussian War to defend Paris. Located to the east of Paris in Villiers-sur-Marne, the fort was part of an outer ring of eighteen major fortifications built in response to improvements in the range and effectiveness of artillery since the construction of the Thiers fortifications of the 1840s. It was built in accordance with improved principles of fortification developed for the Séré de Rivières system.

<span class="mw-page-title-main">Fortified region of Belfort</span>

The fortified region of Belfort formed the first line of defense in the Séré de Rivières system of fortifications in the Belfort Gap. Located in northeastern France between Épinal and Besançon, the primary line was built in the late 19th century to deal with advances in artillery that had made older defensive systems obsolete.

<span class="mw-page-title-main">Fort du Salbert</span>

Fort du Salbert, also known as Fort Lefebvre, was built between 1874 and 1877. It was named after General François Joseph Lefebvre. It forms part of the Séré de Rivières system fortifications in the fortified region of Belfort in northeastern France. It is located at the summit of Salbert hill to the northwest of Belfort. During the early years of the Cold War it briefly served as an air defense coordination center.

<span class="mw-page-title-main">Fort des Basses Perches</span> French Fort

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.

<span class="mw-page-title-main">Fort de Vaujours</span>

<span class="mw-page-title-main">Fort de Bicêtre</span>

The Fort de Bicêtre is a military structure built between 1841 and 1845 during the reign of Louis-Philippe during a time of tension between France and England, in the Paris suburb of Kremlin-Bicêtre. The fort is part of the Thiers Wall fortifications of Paris, built under a program of defensive works initiated by Adolphe Thiers. The fort served as a prison for those involved in the French coup of 1851.

The forts of Metz are two fortified belts around the city of Metz in Lorraine. Built according to the design and theory of Raymond Adolphe Séré de Rivières at the end of the Second Empire—and later Hans von Biehler while Metz was under German control—they earned the city the reputation of premier stronghold of the German reich. These fortifications were particularly thorough given the city's strategic position between France and Germany. The detached forts and fortified groups of the Metz area were spared in World War I, but showed their full defensive potential in the Battle of Metz at the end of World War II.

<span class="mw-page-title-main">Fort d'Issy</span>

Fort d'Issy was one of the fortifications of the city of Paris, France, built between 1841 and 1845. It was one of six forts built to the south of the main wall around the city. The fort was placed too close to the city to be effective, and had a poor design that did not take into account recent experience of siege warfare. It was quickly silenced during the Franco-Prussian War of 1870–71. After the armistice of February 1871 the fort was defended by National Guards of the Paris Commune against the French regular army in April–May 1871. The defense was irresolute and the fort was soon occupied. Today the site of the fort is an "eco-district", an ecologically friendly residential area.
