In the heart of Paris, on the River Seine, the Ile de la Cité (City Island) is considered to be the birthplace of the capital, the core of Gallo-Roman Lutetia, which then spread. Clovis (d.511), king of the Francs, made it his capital and during the time of the Carolingian kings the life of the city was focused around the island. The Ile de la Cite has three unique medieval buildings: the Conciergerie, where Marie-Antoinette was imprisoned and part of which houses today the Palace of Justice; the Sainte Chapelle, built by King Saint Louis, and the Cathedral of Notre-Dame de Paris. This iconic monument and Gothic masterpiece is the most visited building in Paris. Napoleon 1st was crowned emperor there in 1804.
Also worth seeing: the Hotel-Dieu, Paris’ oldest hospital; the Tribunal de Commerce (Trade and Companies Register), built by Napoleon III; the Memorial des Martyrs de la Deportation (Deportation Memorial), inaugurated in 1962; the Pont Neuf, the oldest bridge in Paris.
