Sainte-Chapelle (Holy Chapel), Paris (must see)

The Holy Chapel on the City Island in Paris is a stunning 13th-century example of Rayonnant Gothic architecture. Commissioned by King Louis IX who led the 7th and 8th Crusades to the Holy Land, it was designed as a grand reliquary to house sacred relics, such as the Crown of Thorns purportedly worn by Jesus himself, which Louis acquired in Constantinople.

This two-story chapel has an upper level with remarkable stained-glass windows, reserved for the royal family, while its lower level, adorned with floral designs, served palace courtiers and staff. The Holy Chapel was once part of the medieval City Palace, the former residence of French kings until the 14th century, alongside the neighboring Conciergerie, which later became a prison.

The chapel faced considerable damage over the centuries, particularly during the French Revolution when its sculptures were destroyed, royal emblems defaced, and interiors looted. By the 19th century, extensive restoration efforts were undertaken to revive its medieval charm. Skilled craftsmanship was applied to restore the chapel, making it a blend of medieval and 19th-century artistry. Miraculously, around two-thirds of the original stained glass survived, creating a captivating effect, especially when sunlight illuminates the intricate biblical scenes depicted in the windows.

Architecturally, the Holy Chapel is distinguished by its simplicity and harmony. Unlike many Gothic churches, it lacks flying buttresses, relying instead on deep buttresses and metal supports for stability. A rose window on the west front, added in the 15th century, features scenes of the Apocalypse, while a cedarwood spire captures the essence of Gothic style. The chapel was intended to symbolize Jerusalem, a vision of paradise for the saved at the Last Judgment.

Today, Holy Chapel remains a marvel of medieval design and an enduring symbol of King Louis IX’s devotion and legacy.
