Ile de la Cité, once known as Lutetia, is the oldest settlement in Paris, and boasts more than its fair share of Paris sights: the Pont Neuf, the Pont de l’Archevêché and Notre Dame cathedral, to name only three. Its location bang in the middle of Paris, with Châtelet to the north and Saint-Germain-des-Prés to the south, makes it the central crossroads of the city, which grew outwards from here. When you’ve finished visiting all the sights, take one last admiring look at the magnificent facade of Notre Dame, then stroll along the banks of the Seine and stop to watch improvised concerts by wandering musicians, for whom this area is a prime performance venue. Ile de la Cité is also the perfect place for a riverside picnic. At night, the bridges are beautifully lit, and there is a feeling of midsummer magic.
