Up until the mid-19th century, The Ile de la Cité was mostly occupied by houses and shops, but later became a major administrative and bureaucratic center. In addition to monuments such as Notre Dame, the Sainte Chapelle chapel, la Conciergerie (where Marie Antoinette awaited her execution during the French Revolution) and the Holocaust Memorial, the Ile de la Cite also houses the Prefecture de Police (police headquarters) and the Palais de Justice, the city's historic and principle court of justice.
The island is part of Paris' 1st arrondissement to the west and 4th arrondissement to the east. To get there, get off at Metro Cite or RER Saint Michel.
