An icon in flames

The mammoth blaze that tore through the Notre Dame Cathedral in Paris nearly destroyed the 850-year-old landmark, alarming worshippers and admirers around the world. The church’s wood latticework roof and iconic spire collapsed, but many of its most valuable religious relics and cultural treasures were spared. Here’s an interactive look at what was lost and what was rescued.

The Spire

The cathedral’s iconic spire — known in France as “la fléche,” or arrow — was one of the most recognizable sights in all of Paris before it was destroyed by flames.

It was surrounded by 16 copper statues representing the 12 apostles and the four evangelists; the statues were safely removed last week as part of a restoration effort.

The roof

The cathedral’s roof, known as “The Forest” because of its long planks of 800-year-old wood, collapsed in the fire and cannot be rebuilt in its original form, officials said. The roughly 330-foot roof, where the fire broke out, was one of the oldest of its kind in Paris, according to the cathedral’s website.

The rose window

The cathedral’s world-famous stained-glass rose windows appeared to have been spared by the inferno. The 13th-century South Rose Window, created in 1260 and offered by King St. Louis, spans roughly 33 feet across and symbolizes Jesus sitting in Heaven, “surrounded by all those who have been his witnesses on Earth,” according to the cathedral’s website.

The Great Organ

The cathedral’s great organ and its 8,000 pipes escaped destruction. “Le Grand Orgue,” as it’s known in French, dates to the 1730s and was built by Francois Thierry, a member of a family of major organ builders.

The Tunic of St. Louis

The long, shirt-like garment known as the tunic of St. Louis survived the fire, according to French Culture Minister Franck Riester. It is believed to have once belonged to King Louis IX, who reigned in France from 1226 to 1270. The tunic was saved by first responders, the Paris mayor tweeted.

The Crown of Thorns

The cathedral is home to a treasured relic: the crown of thorns that is believed to have been worn by Jesus as he was crucified, first brought to Paris by King Louis IX in the 13th century. The wreath was rescued from the mammoth blaze.
