Île de la Cité, Île Saint-Louis … islands in Paris are special places not to miss. Two islands in the heart of Paris are particularly appealing to tourists: the Île Saint-Louis and the Île de la Cité have some of the finest monuments in Paris, and their quaysides are wonderful places to stroll and enjoy a picnic. The unassuming Île Saint-Louis retained its tranquility and elegance, whilst on the Île de la Cité a palace and a cathedral were built. Today, visitors flock to see landmark sites including the Cathedral of Notre-Dame de Paris, Sainte-Chapelle … and discover with surprise and delight the elegance and refinement of hôtels particuliers on the adjacent Île Saint-Louis. Linked by a bridge, these two islands on the Seine are inseparable.
