Origins and construction
Construction of the Digue du Large dates back to the mid-19th century, a period marked by major infrastructure works. The project was initiated in 1844 under the reign of Louis-Philippe and continued to evolve under Napoleon III. The breakwater was a direct response to the need to modernise the port andincrease its capacity to accommodate ever-largerships, in line with growing industrialisation.
Today the breakwater stretches for almost 7 kilometres from the entrance to the Old Port to l’Estaque.
Developments and improvements
Over the years, the Digue du Large has undergone a number of modifications and extensions. Initially designed as a purely functional structure, it has been strengthened and lengthened several times to meet the changing needs of the port and the challenges posed by erosion and weather conditions. Each modification has contributed to its robustness, making it an impressive monument today and an integral part of the port’s infrastructure. It was completed in 1925. A protective shield for the port, it plays a crucial role in maritime safety.
