Paris, often referred to as the "City of Light," is renowned for its iconic landmarks like the Eiffel Tower, Notre-Dame Cathedral, and the Louvre Museum. Yet, beneath the romantic streets and grand boulevards lies a secret world that's less celebrated but equally fascinating—the Paris Sewer Museum. This unique attraction offers an intriguing glimpse into the city's underbelly, where a network of tunnels, passageways, and sewers weaves a story of engineering marvels, history, and urban development.

A Journey Beneath the Streets

The Paris Sewer Museum, also known as Musée des Égouts de Paris, traces its roots back to the early 19th century. It all began with the vision of the French engineer Eugène Belgrand, who initiated the construction of a modern sewer system in Paris. His goal was to rid the city of rampant diseases caused by unsanitary living conditions and overcrowding. As a result, this ambitious project aimed to create a cleaner, healthier Paris.

Located in the heart of Paris, the Sewer Museum offers a unique perspective on the city's development. Situated beneath the Quai d'Orsay, along the Seine River, it provides visitors with a direct view of the city's sewer system, which stretches over 2,100 kilometers (approximately 1,305 miles).

Unveiling the Secrets

Upon entering the museum, visitors are transported to a fascinating world below the streets. The dimly lit tunnels, complemented by an audio guide, reveal the evolution of Paris's sewer system and the critical role it played in the city's transformation.

The museum's exhibits include an array of artifacts, including antique machinery, tools, and photographs that chronicle the growth of the sewer system. One of the most captivating displays is a collection of vintage photographs showing how the sewers were built, highlighting the incredible craftsmanship of the engineers and laborers who constructed them.

The museum features several interactive exhibits that provide a tactile understanding of how the sewers function. For instance, you can observe a portion of the actual sewer system with flowing water beneath a glass floor—a rare sight that evokes awe and fascination.

The Paris Sewer System

The sewers showcased at the museum are still functional today. This means they not only serve as a historical display but also continue to play an essential role in the city's waste management and sanitation. Visitors can appreciate the complexity of the sewer system, designed to handle both rainwater and wastewater.

With a blend of engineering precision and human effort, the sewers of Paris are meticulously maintained. Museum visitors can learn about the daily work carried out by sewer workers and the importance of preventing blockages and ensuring the proper flow of waste.

A Journey into Urban Development

By exploring the Sewer Museum, you embark on a journey through time and space, gaining insight into the evolution of a modern city. Paris's sewer system is not merely an intricate network of tunnels but a testament to human ingenuity and the progress achieved in the face of adversity.

The Paris Sewer Museum is a hidden gem beneath the city's picturesque streets, offering an educational, eye-opening, and thought-provoking experience. It unveils a lesser-known aspect of Paris's history and the extraordinary efforts to transform the city into the magnificent metropolis it is today. So, if you ever find yourself in the "City of Light," don't hesitate to take a fascinating journey beneath the streets, as the Paris Sewer Museum invites you to explore a world that is as significant as it is unseen.

Indian Railways Launches First Hydrogen-Powered Train on Jind–Sonipat Route

Published on July 20, 2026

Indian Railways has introduced the country's first indigenously built hydrogen-powered passenger train, marking a significant step in its clean transportation journey. Named NaMo Green Rail, the train will operate on the Jind–Sonipat section of Northern Railway in Haryana.

Prime Minister Narendra Modi inaugurated the hydrogen-powered locomotive ahead of its maiden journey, describing the launch as an important milestone in India's vision of becoming both self-reliant and environmentally sustainable.

With the launch, India joins a select group of countries, including Germany, Japan, China and the United States, that have introduced hydrogen-powered passenger rail services. Germany was the first country to launch a commercial hydrogen-powered train fleet in 2022.

Designed, engineered and built entirely in India, NaMo Green Rail emits only heat and water vapour, making it a zero-emission alternative to diesel-powered trains. The initiative forms part of the government's broader efforts to expand hydrogen-based mobility and reduce carbon emissions across the transport sector.

The 10-coach train has a seating capacity of around 2,600 passengers and can operate at speeds of up to 75 km/h. It will run two return trips daily on the 90-kilometre route connecting Jind and Sonipat.

One of the key highlights of the new service is its affordable pricing. According to railway officials, ticket fares start at ₹5, with the highest fare capped at ₹25, depending on the distance travelled. Passengers on the inaugural service were also able to purchase tickets priced at ₹5.

Although Indian Railways has already electrified nearly all of its 70,000-kilometre rail network, hydrogen-powered trains provide a practical solution for routes where complete electrification may not be feasible.

The introduction of NaMo Green Rail aligns with the government's ambition to make Indian Railways net-zero by 2030, while supporting India's wider clean energy goals through increased adoption of hydrogen, renewable energy and other sustainable technologies.

Commenting on the launch, Aditya Arya, Co-Founder and CEO, Yes Madam, said, "Yes Madam has consistently been a disruptor in the at-home beauty and wellness industry. We introduced mono-dose kits to improve hygiene and brought greater pricing transparency by separating product and service costs at a time when no one else in the industry was doing so.
