Île de la Cité

The Île de la Cité (French pronunciation: ​[il də la site]) is one of two remaining natural islands in the Seine within the city of Paris (the other being the Île Saint-Louis). It is the centre of Paris and the location where the medieval city was refounded.

The western end has held a palace since Merovingian times, and its eastern end since the same period has been consecrated to religion, especially after the 10th century construction of a cathedral preceding today's Notre Dame. The land between the two was, until the 1850s, largely residential and commercial, but has since been filled by the city's Prefecture de Police, Palais de Justice, Hôtel-Dieu hospital and Tribunal de commerce. Only the westernmost and northeastern extremities of the island remain residential today, and the latter preserves some vestiges of its 16th-century canon's houses. The Mémorial des Martyrs de la Déportation, a memorial to the 200,000 people deported from Vichy France to the Nazi concentration camps during the Second World War, is located at the upriver end of the island.

Most scholars believe that in 52 BC, at the time of Vercingetorix's struggle with Julius Caesar, a small Gallic tribe, the Parisii, lived on the island. At that time, the island was a low-lying area subject to flooding that offered a convenient place to cross the Seine and a refuge in times of invasion. However, some modern historians believe the Parisii were based on another, now eroded island. After the conquest of the Celts, the Roman Labienus created a temporary camp on the island, but further Roman settlement developed in the healthier air on the slopes above the Left Bank, at the Roman Lutetia.
