The Île de la Cité is one of two natural islands in the Seine. It is the centre of Paris and the location where the medieval city was refounded.
Clovis established a Merovingian palace on the island, which became the capital of Merovingian Neustria.
The Île de la Cité remains the heart of Paris. All road distances in France are calculated from the "zero kilometer" point located in the Place du Parvis de Notre-Dame, the square facing Notre-Dame''s west end-towers.
