Origin and history

The canal Saint-Martin, 4.55 km long, was designed at the beginning of the 19th century to meet the growing needs of drinking water in Paris, then confronted with epidemics linked to the pollution of the Seine and Bièvre. The project, initiated under Napoleon Bonaparte in 1802, takes up an ancient idea of the Ourcq pipeline, a river about 100 kilometers northeast. The construction, delayed by the Napoleonic wars, was relaunched under Louis XVIII and entrusted to the engineer Pierre-Simon Girard. The Compagnie des Canaux de Paris, founded in 1818, won the award in 1821, and the works began in 1822. The canal was finally inaugurated by Charles X on 4 November 1825, becoming an essential link in the Parisian hydraulic system.

In the second half of the 19th century, under the impetus of Prefect Haussmann, the canal was partially covered to facilitate land and military traffic in the working-class neighborhoods of northeastern Paris. Between 1860 and 1862 vaults were built at Richard-Lenoir Boulevards and Bastille Boulevards, while the level of the canal was lowered by 5.5 m to allow navigation under these new structures. In 1866, an imperial decree authorized the extraction of water in the Marne River to maintain the flow of the canal, with the construction of a building plant in Villers-lès-Rigault and Trilbardou. At its peak, between the 19th century and the middle of the 20th century, the canal carried goods, cereals and materials, making the basin of the Villette the 4th French port in 1882.

In the 20th century, the canal experienced a gradual decline with competition from road and rail transport, resulting in the closure of factories and warehouses along the river. In the 1960s, an urban motorway project even threatened its existence, before being abandoned in 1971. Ranked a historic monument in 1993, the canal becomes a place for walking and leisure, while remaining a symbol of the social transformations of Paris, as evidenced by the waves of gentrification of the surrounding neighborhoods since the 2000s. Today, it hosts tourist cruises, picnics and a variety of wildlife, while maintaining its role in collective memory, notably through cinema and literature.

The Saint Martin Canal is also marked by contemporary issues, such as the settlement of refugees since 2006, mainly from Afghanistan and Central Asia. These precarious camps, often dismantled, raise questions about reception policies and the rights of asylum seekers. At the same time, the canal remains a major cultural space, inspired by artists such as Alfred Sisley, Marcel Carné or Jean-Pierre Jeunet, and a place of biodiversity with 303 plant species and 90 species of birds.

Technically, the canal requires regular maintenance operations, such as lock drains and cleanings, in line with the work carried out in 2016. These interventions help to preserve its infrastructure, while sometimes revealing structural challenges, such as the dissolution of the gypsum under the Louis-Blanc basin, leaving the canal to rest on a vacuum. Despite these challenges, the Canal Saint-Martin remains a living heritage, both a witness to the industrial history of Paris and a contemporary living space.
