13th-century Gothic royal chapel commissioned by Louis IX to house his collection of Passion relics. The upper chapel features 15 stained-glass windows depicting 1,113 biblical scenes — the most complete ensemble of 13th-century stained glass in the world. The light inside on a sunny day is transcendent.

Buy a combination ticket with the Conciergerie next door — same security queue, better value. Arrive early or late to avoid tour groups. Ascend the narrow spiral staircase to the upper chapel and let your eyes adjust. The windows tell stories from Genesis to the Resurrection in glass that has survived 750 years. Sit in the pews and look up.
Morning when sunlight floods the chapel from the east. Sunny days are essential — the stained glass on a grey day loses half its impact. Avoid midday tour-group rushes.
Built 1242–1248 by Louis IX (later Saint Louis) to house Christ's Crown of Thorns and other relics acquired from the Byzantine emperor. The chapel survived the Revolution — the relics were moved to Notre-Dame, the stained glass was hidden. Two-thirds of the glass is original 13th-century work. The chapel was part of the royal palace complex on Île de la Cité. Security queues can be long due to the Palais de Justice location. This is the single best example of Rayonnant Gothic architecture in existence.
