The Seine’s dark and dirty past (and its clean comeback)

It was once a garbage dump, now it’s a cruise highlight

In the 19th century, the Seine was so polluted that even diseased animals were dumped in it. Sewage, industrial waste, and carcasses filled the river, making it foul and dangerous. After more than a century of cleanup, it’s now one of Europe’s most scenic cruise routes: clean, safe, and beloved by tourists and locals alike.

Ghost stories beneath the riverbanks

The Seine has witnessed a long, often tragic history, from royal executions to drownings during floods. Locals whisper about the mysterious ‘Lady in Black’ who is said to haunt the bridges near Notre-Dame Cathedral. 

Secret tunnels lie beneath you

Few tourists know that as you cruise on the Seine, you’re actually floating above a maze of hidden Roman and World War II tunnels. These tunnels were used for smuggling, secret military operations, and even royal escape routes.

Kids onboard? They’ll love solving riddles and discovering stories with the “Seine and its Secrets” cruise experience.

Geography that’ll surprise you

You’re cruising through the soul of Paris

The Seine is more than water; it’s where Paris began. The city was born on a small island in the river, Île de la Cité. As you cruise past the Eiffel Tower, Notre-Dame, and the Louvre, you’re not just sightseeing but gliding through 2,000 years of Parisian history. It’s the same river that kings, artists, and revolutionaries once looked upon.

37 unique bridges, each with a backstory

The Seine flows beneath 37 bridges in Paris, each with its own secret. Pont Neuf is the oldest, despite its name meaning “new.” Pont Alexandre III dazzles with gold and grandeur. Pont des Arts once groaned under the weight of thousands of love locks. As your boat glides under them, you’re not just passing bridges, you’re sailing through centuries of Parisian stories.

The green water isn’t pollution

Many first-time visitors think the green tint of the Seine means it’s polluted. In fact, the color comes from a mix of natural algae and minerals like chalk in the water. On sunny days, this gives the river a glowing, even fluorescent look. It’s a natural part of the Seine’s ecosystem, not something to worry about!

Culture, art, and literary legends

Monet captured its moods in paintings like “La Seine at Vétheuil” and “Barges on the Seine”. Renoir painted “The Seine at Asnières”, while Van Gogh immortalized it in works like “Bridges across the Seine at Asnières”.

Masterpieces were created right where your cruise floats today. It’s the same river that sparked some of the world’s greatest art.

Across from Notre-Dame sits a little bookstore with a big past – Shakespeare and Company. Hemingway, Joyce, and Fitzgerald once spent time here. 

Some even slept among the shelves. It was a safe haven for writers chasing their dreams.

Modern-day cruise magic

The Eiffel Tower sparkles every hour and is best seen from the river

Each summer, the Seine turns tropical. Sand, palm trees, and sun loungers pop up along the river, yes, real beaches in the heart of Paris. Locals sunbathe, sip wine, and watch boats float by. It’s the city’s coolest warm-weather secret.

VIP cruises exist for a reason

History, you can sail through

Paris’s first highway was the Seine

In the 1600s, boats brought wine, grain, and animals into Paris along the Seine. It was the city’s main transport route. So much cargo came through that parts of the riverbank collapsed. Today, tourists sail where traders once rushed.

UNESCO World Heritage views

The Seine riverbanks, from the Eiffel Tower to Île Saint-Louis, are a protected UNESCO World Heritage Site. This stretch is full of historic buildings, bridges, and memorable views. A simple cruise turns into a journey through centuries of Parisian beauty and culture.

A witness to revolutions and coronations

The Seine has seen kings crowned and revolutions unfold. Napoleon’s funeral passed by the river. During the French Revolution, some bridges were used for executions. Today, the calm waters quietly carry stories of power, glory, chaos, and unforgettable moments in history.
