In the series "Once Upon a Time... the Discoverers," the Maestro lets off some steam. Some two thousand years ago, Heron invented the steam machine in Alexandria, but it took two millenia to perfect the invention and put it to practical use.

In part two of this series, "Once upon a Time... the Discoverers," Maestro talks about Cugnot, the inventor of the steam traction engine.

Years of research and trial and error culminated in the invention of the first locomotive on rails. Not bad for a father-and-son experiment. That's what Murdoch and his son George achieved in 1797.

George Stephenson tries out his invention, a steam locomotive. He allows his son, Robert, to ride on it as long as he stays on the edge of the carriage and gets ready to jump off if the rails buckle under the weight of the locomotive... which they do. Luckily his son followed his instructions!

The future of the railroad depends on whether George Stephenson's locomotive, 38 cars long, will run or not. The local townspeople debate whether it will go full speed ahead or not budge at all due to its size.

This next part of the Il était une fois series on George Stephenson deals with the Rainhill Trials, a competition that determined what kind of trains (steam engines or locomotives) would be used on the Liverpool and Manchester Railway.

This last part of the Il était une fois episode on George Stephenson deals with the Rainhill Trials, a competition that determined what kind of trains (steam engines or locomotives) would be used on the Liverpool and Manchester Railway. Stephenson proves to be the best competitor.

This video is all about the people of France, from the ancient Franks and Gauls to the present-day population, which currently numbers over sixty-six million inhabitants.

Marion takes us along Paris's Canal Saint Martin, which is part of a waterway network that measures one hundred thirty kilometers long. In their heyday, the Parisian canals were the main means of transportation of goods and materials, and even drinking water! Nowadays, historic buildings, restaurants, and concert halls are the main attractions along the canals.

It's been said that Paris is the most romantic city in the world. In this video, you will discover the origin of the word "romantic" and learn about the romanticism movement, which originated not from France as one might expect, but from England and Germany and later took hold in France.

The Underwater Museum of Lorient might be a little hard to get to, given that it's literally underwater. Dedicated to shipwrecks and other sunken objects, the museum is made possible by a team of volunteers with a passion for documenting these lost treasures at the bottom of the ocean.

Have you ever eaten an orache or a cardoon? Though popular in the Middle Ages, these vegetables are rarely harvested nowadays. But you'll find them in the garden of the Abbaye du Relec (Relec Abbey) in Brittany, which contains vegetables from many different time periods and countries.

This video takes an in-depth look at the curious French idiom mener une vie de bâton de chaise (to lead a chair-pole life). Though the life of a chair pole might not seem very interesting, the history behind the idiom certainly is!

Daniel introduces the charming town of Compiègne and its magnificent City Hall. In the City Hall building, you'll find the Bancloque, a fourteenth-century bell that still rings today with the help of three automated figures called jacquemarts that "poke" the bell on the hour. And make sure to stop by the burger kiosk on your way out of the city for a delicious, locally sourced treat!

As Daniel explains, Joan of Arc is a bit of an "obsession" among French people, and tributes to her can be found in many towns across France. Compiègne has particularly close ties to the country's patron saint—after assisting the town in its fight against the Burgundians, she was captured by them in 1430.
