Lille is a city in the northern part of France, in French Flanders. On the river Deûle, near France's border with Belgium, it is the capital of the Hauts-de-France region, the prefecture of the Nord department, and the main city of the European Metropolis of Lille.

Nicknamed in France the "Capital of Flanders", Lille and its surroundings belong to the historical region of Romance Flanders, a former territory of the county of Flanders that is not part of the linguistic area of West Flanders. A garrison town (as evidenced by its Citadel), Lille has had an eventful history from the Middle Ages to the French Revolution. Very often besieged during its history, it belonged successively to the Kingdom of France, the Burgundian State, the Holy Roman Empire of Germany and the Spanish Netherlands before being definitively attached to the France of Louis XIV following the War of Spanish Succession along with the entire territory making up the historic province of French Flanders. Lille was again under siege in 1792 during the Franco-Austrian War, and in 1914 and 1940. It was severely tested by the two world wars of the 20th century during which it was occupied and suffered destruction

A merchant city since its origins and a manufacturing city since the 16th century, the Industrial Revolution made it a great industrial capital, mainly around the textile and mechanical industries. Their decline, from the 1960s onwards, led to a long period of crisis and it was not until the 1990s that the conversion to the tertiary sector and the rehabilitation of the disaster-stricken districts gave the city a different face. Today, the historic center, Old Lille, is characterized by its 17th-century red brick town houses, its paved pedestrian streets and its central Grand'Place. The belfry of the Hôtel de ville de Lille (Lille City Hall) is one of the 23 belfries in the Nord-Pas-de-Calais and Somme regions that were classified as UNESCO World Heritage Sites in July 2005, in recognition of their architecture and importance to the rise of municipal power in Europe.
