The fate of many of Notre Dame's treasures is still unknown after the huge fire torn by the 850-year-old cathedral on Monday.
Experts are entering the wreck of the Paris landmark today to see which of the precious works of art and religious relics have been saved.
The mayor of Paris said that one of the most irreplaceable objects – the crown of thorns known to have been worn by Jesus at his crucifixion – was safe tonight.
But there are fears for the 13th-century stained glass windows and the magnificent organ of the church, while the wooden roof and the ornate spire have disappeared.
Safe: crown of thorns
One of the cathedral's most valuable items, a remnant believed to be the crown of thorns bearing Jesus Christ on the cross, was taken away to a secure facility.
Reports in France stated that the chaplain of the Paris fire brigade had gone in with the fire brigade to save the crown.
Experts said the irreplaceable item is in a & # 39; very safe place & # 39; was saved.
The & # 39; Crown of Thorns & # 39; which is said to have been worn by Jesus Christ at his crucifixion, depicted in Notre Dame cathedral, has been rescued from the fire of Monday evening
Safe: tunic from St. Louis
A 13th-century linen tunic thought to belong to King Louis IX – canonized as St. Louis – was also secured, the mayor of Paris said.
In his 44-year reign, Louis participated in the Crusades and certain early principles of justice, such as the presumption of innocence.
He was proclaimed a saint in 1297 – the only French prince to receive the honor – and was responsible for acquiring the Crown of Thorns.
Safe: images flew up from the roof
Renovation was already taking place in the cathedral – possibly in connection with the fire.
As part of that work, 16 copper statues were flown by air just before the fire away from the now-destroyed spire.
Some copper statues, including this statue of Saint John, were removed from the top of Notre Dame a few days before the eruption of the Cathedral of Paris
Apparently safe: descent from the cross
This 1723 statue by Nicolas Coustou sits on the high altar of the cathedral. It shows that Jesus was taken from the cross after his crucifixion.
The first photos still showed the cross with part of the sculpture visible, although it was surrounded by smoke and debris.
The cross and the statue on the altar of Notre Dame – sculpted by Nicolas Coustou in 1723 – were apparently intact after the blaze but surrounded by smoke and debris
Apparently safe: cathedral bells
Despite the fire rushing through the roof of Notre Dame, firefighters were able to prevent the fire from consuming the main structure of the cathedral, including the two bell towers.
The clocks that went out at key moments in the history of France were considered safe.
The two bell towers of the cathedral were still extinguished this morning with fire, which offered some hope to the Parisians who feared that the entire building would collapse
Unknown: North, West and South Rose Windows
The beautiful stained glass artworks in the cathedral date from the 13th century.
A French journalist on the scene last night said the north window turned out to be safe without any sign of broken glass, although firefighters remained concerned.
There are conflicting reports about the fate of the other two windows, but a picture of this morning seemed to leave the south largely intact.
Architecture professor Julio Bermudez said that the stained glass windows & # 39; really irreplaceable & # 39; goods.
This photo seemed to show the North Rose Window intact on Tuesday morning, but the fate of the other stained glass masterpieces was still unclear
Unknown: Grand Organ
The status of the great organ of Notre Dame was still unknown on Tuesday morning.
The organ, whose beginnings began in 1401, was renovated in 2013 when the cathedral celebrated its 850th anniversary.
Each of the nearly 8,000 pipes, some of which date from the 18th century, was individually cleaned and returned to its place while nine new, gigantic clocks replaced the nineteenth century.
The pipes of the large organ of the cathedral – which were cleaned in 2013 – are under one of the stained glass windows. It is unclear whether the organ has been damaged in the fire
Unknown: True Cross and Holy Nails
Another relic of the cathedral is an alleged piece of the True Cross – precisely the instrument on which Jesus was crucified in the first century AD.
The collection also contains a nail that is said to be of the cross.
It was unclear Tuesday morning whether they had been saved together with the Doornenkroon.
A well-known piece of the True Cross – the instrument on which Jesus was crucified – is one of the relics in the Notre Dame collection
Unknown: image of the Madonna and the Child
The 14th-century, life-size statue of the Virgin Mary and the baby Jesus is also known, just like the cathedral itself, as Notre Dame or Our Lady.
It is close to the Descent from the Cross sculpture that apparently escaped destruction, but its own destiny is still unclear.
A statue of the Virgin Mary with a baby Jesus Christ, sculpted in the 14th century, is one of the treasures that are still not explained in Notre Dame
Unknown: Statue of St Denis
This sculpture, which began in 1853, shows St Denis, the patron saint of the city of Paris and a Christian martyr from the 3rd century AD.
The statue in Notre Dame shows that he held his severed head after he was executed, but his fate is still unknown today.
Destroyed: irreplaceable wooden roof
The wooden roof of the cathedral – built with beams made from old forests over 800 years ago – was burned to ashes in the fire.
A French expert on cultural heritage has said that France no longer has trees large enough to replace them.
He said the restoration work should use new technologies to rebuild the roof.
The wooden roof was destroyed by the smoke and flames of the 12th-century cathedral. Experts said that France no longer had the trees to replace it in the same way
Destroyed: 19th century spire
Parisians watched with embarrassment as the spire burned and then collapsed in the intense heat of the blaze.
The 13th-century tower was dismantled during the French Revolution and later rebuilt in the 1860s.
The spire of Notre Dame collapsed last night. This was made in the 19th century after the original medieval spire was destroyed during the French Revolution
