6Sainte-Chapelle
Sainte-Chapelle, located on the Île de la Cité, is an extraordinary example of Gothic architecture. Built in the 13th century by King Louis IX to house his collection of Christian relics, this royal chapel is known for its stunning stained glass windows. The windows, which reach nearly 50 feet high, cover the walls in vibrant scenes from the Bible. This “jewel box” of Parisian architecture captivates visitors with its ethereal beauty and serves as a reminder of the city’s medieval past.
