Boulogne-sur-Mer, Pas-de-Calais Département, Hauts-de-France, France

🇫🇷 Boulogne-sur-Mer, often called just Boulogne, is a coastal city in Northern France. It is a sub-prefecture of the department of Pas-de-Calais. Boulogne lies on the Côte d'Opale, a touristic stretch of French coast on the English Channel between Calais and Normandy, and the most visited location in the region after the Lille conurbation. Boulogne is its department's second-largest city after Calais, and the 183rd-largest in France. It is also the country's largest fishing port, specialising in herring.

Boulogne is an ancient town and was the main Roman port for trade and communication with its Province of Britain. After a period of Germanic presence following the collapse of the Empire, Boulogne was integrated into the County of Boulogne of the Kingdom of France during the Middle Ages. It was occupied by the Kingdom of England numerous times due to conflict between the two nations. In 1805 it was a staging area for Napoleon's troops for several months during his planned invasion of the United Kingdom.

The city's 12th-century belfry is recognised by UNESCO as a World Heritage Site (along with other belfries of Belgium and France), while another popular attraction is the marine conservation centre Nausicaa.

History The foundation of the city known to the Romans as Gesoriacum is credited to the Celtic Boii. In the past, it was sometimes conflated with Caesar's Portus Itius, but that is now thought to have been a site near Calais which has since silted up. A tall lighthouse was built at Gesoriacum circa 39 AD by order of the Emperor Caligula, possibly in preparation for an invasion of Britain. Known as the Tour d'Ordre, coastal erosion caused it to topple into the sea in 1644.

The Tour d'Ordre, a Roman lighthouse, in 1550. It fell into the sea in 1644, having stood for over 1600 years.

From the time of Claudius's invasion in AD 43, Gesoriacum formed the major port connecting the rest of the empire to Britain. It was the chief base of the Roman navy's Britannic fleet until the rebellion of its admiral Carausius in 286. As part of the imperial response, the junior emperor Constantius Chlorus successfully besieged it by land and sea in 293. The name of the settlement was changed to Bononia at some point between the sack of Gesoriacum and 310, possibly as a consequence of its refounding or possibly by the replacement of the sacked and lower-lying city by another nearby community.

The city was an important town of the Morini (the 'sea people'), and Zosimus called it Germanorum ("Germanic-speaking") at the end of the 4th century.

History: Middle Ages Further information: Siege of Boulogne (1492) and Sieges of Boulogne (1544–46)

In the Middle Ages Boulogne was the capital of an eponymous county, founded in the mid-9th century. An important Count, Eustace II, assisted William the Conqueror in his conquest of England. His wife founded the city's Notre Dame cathedral, which became a site of pilgrimage from the 12th century onwards, attended by fourteen French kings and five of England. It was an important whaling centre prior to 1121. The city survived on herring fishing and received its municipal charter from Count Renaud of Dammartin in 1203.

The area was fought over by the French and the English, including several English occupations during the course of the Hundred Years War. In 1492 Henry VII laid siege to Boulogne before the conflict was ended by the Peace of Étaples. Boulogne was again occupied by the English from 1544 to 1550. In 1550, The Peace of Boulogne ended the war of England with Scotland and France. France bought back Boulogne for 400,000 crowns. A culture of smuggling was present in the city until 1659, when French gains in Flanders from the Treaty of the Pyrenees moved the border northwards.

History: 19th century Boulogne received its current status as a subprefecture of the Pas-de-Calais department in 1800 due to the territorial re-organisation in Revolutionary France. France became the French Empire in 1804; in 1803 Boulogne became an Imperial City (Ville Impériale).

The 19th century was a prosperous one for Boulogne, which became a bathing resort for wealthy Parisians after the 1848 completion of the Longueau–Boulogne railway connecting the town with the French capital. In the 19th century, the Basilica of Notre-Dame de Boulogne was reconstructed by the priest Benoît Haffreingue, who claimed to have received a call from God in 1820 to reconstruct the town's ruined basilica. During the Napoleonic Wars, Napoleon amassed La Grande Armée in Boulogne to invade the United Kingdom in 1805. However, his plans were halted by other European matters and by the supremacy of the Royal Navy.

A nephew of Napoleon Bonaparte, Louis-Napoleon Bonaparte (subsequently the emperor Napoleon III), returned to France in secret from his exile in Britain, passing through Boulogne in August 1840. He was later jailed for trying to lead a revolt in Strasbourg.

World wars During the First World War, this was the entrepôt for the first unit of the British Expeditionary Force to land in France and for many others thereafter. Boulogne was one of the three base ports most extensively used by the Commonwealth armies on the Western Front throughout the First World War. It was closed and cleared on 27 August 1914 when the Allies were forced to fall back ahead of the German advance, but was opened again in October and from that month to the end of the war, Boulogne and Wimereux formed one of the chief hospital areas.

Until June 1918, the dead from the hospitals at Boulogne were buried in the Cimetiere de L'Est, one of the town's cemeteries, the Commonwealth graves forming a long, narrow strip along the right hand edge of the cemetery. In the spring of 1918, it was found that space was running short in the Eastern Cemetery in spite of repeated extensions to the south and the site of the new cemetery at Terlincthun was chosen. It also was the site of an Allied (French and British) armaments production conference.

On 22 May 1940 during the Battle of France, two British Guards battalions and some pioneers attempted to defend Boulogne against an attack by the German 2nd Panzer Division. Despite fierce fighting, the British were overwhelmed and the survivors were evacuated by Royal Navy destroyers while under direct German gunfire. On 15 June 1944, 297 aircraft (155 Avro Lancasters, 130 Handley Page Halifaxes, and 12 De Havilland Mosquitos) of the Royal Air Force bombed Boulogne harbour to suppress German naval activity following D-Day. Some of the Lancasters carried Tallboy bombs and the harbour and the surrounding area were completely destroyed. In August 1944 the town was declared a "fortress" by Adolf Hitler but it succumbed to Operation Wellhit, the assault and liberation by the 3rd Canadian Infantry Division in September. In one incident, a French civilian guided the Canadians to a "secret passage" leading into the walled old town and by-passing the German defenders.

To replace the destroyed urban infrastructure, affordable housing and public facility projects in functional, brutalist building styles were carried out in the 1950s and 60s.
