Boulogne-sur-Mer is a lively coastal city in Northern France. People often just call it Boulogne. It's located in the Pas-de-Calais area, right on the English Channel.

This city is part of the beautiful Côte d'Opale, a popular French coastline. It's the second-largest city in its department, after Calais. Boulogne is also famous for being France's biggest fishing port, especially known for herring.

Boulogne is a very old city with a rich history. The Romans used it as a main port to connect with Britain. Later, during the Middle Ages, it became part of the Kingdom of France.

The city was often fought over by France and England. In 1805, Napoleon gathered his troops here, planning to invade the United Kingdom.

Today, Boulogne has a 12th-century belfry (bell tower) that is a UNESCO World Heritage Site. Another popular spot is Nausicaa, a cool marine conservation center.

What's in a Name?

The name Boulogne comes from the Latin word Bononia. This word might mean "foundation," "citadel," or "granary" in an old Celtic language.

The "sur-Mer" part means "on sea" in French. This helps tell it apart from Boulogne-Billancourt, a town near Paris. That town's name actually comes from a church dedicated to "Our Lady of Boulogne[-sur-Mer]".

A Look Back in Time

How Boulogne Began

The city, once called Gesoriacum by the Romans, was first settled by the Celtic Boii tribe. Around 39 AD, the Roman Emperor Caligula ordered a tall lighthouse, the Tour d'Ordre, to be built here. This was possibly to prepare for an invasion of Britain. Sadly, the lighthouse fell into the sea in 1644 due to coastal erosion.

From 43 AD, Gesoriacum was the main port connecting the Roman Empire to Britain. It was a key base for the Roman navy. Later, the city's name changed to Bononia.

The Middle Ages

In the Middle Ages, Boulogne was the capital of its own county. A famous Count, Eustace II of Boulogne, helped William the Conqueror take over England. His wife started the city's Notre Dame cathedral. This cathedral became a popular place for pilgrimages, visited by many kings.

The city was important for herring fishing. It also got its official city rights in 1203. France and England often fought over the area. The English occupied Boulogne several times during the Hundred Years War. In 1550, France bought Boulogne back from England.

The 19th Century

The Column of the Grande Armée remembers Napoleon gathering 200,000 soldiers near Boulogne. He planned to invade the United Kingdom from here.

In 1800, Boulogne became a "subprefecture" in France. It was even called an "Imperial City" in 1803. The 1800s were a good time for Boulogne. It became a popular beach resort for wealthy Parisians. This happened after a railway connected the city to Paris in 1848.

During the Napoleonic Wars, Napoleon gathered a huge army in Boulogne. He planned to invade the United Kingdom in 1805. However, his plans changed due to other events in Europe and the strong British navy.

In September 1944, the city was liberated by Canadian forces. After the war, new buildings were constructed to replace what was destroyed.
