The Notre Dame Cathedral is opening its doors to worshipers on Saturday, marking the first time since a devastating fire tore through its halls in April.
The diocese of Paris announced that a mass will be held on Saturday evening with only about 30 people, including clerics, worshipers and media, in attendance.
Those attending the mass will be required to wear hard hats for safety, Géraldine Delmarre, press officer of the Paris diocese, confirmed to ABC News.

The date signifies an anniversary of sorts for the cathedral: the consecration of the church’s altar, known as the feast of the Dedication of Our Lady, is normally celebrated annually on June 16.

On April 15, a blaze that took hours to extinguish tore through the 850-year-old building in the heart of France’s capital.
The fire was ignited during an evening mass at the start of Holy Week, the busiest and most important period of the liturgical year.
Millions mourned the extent of the destruction in the landmark of Gothic architecture, but miraculously, much of the relics and structure of the cathedral survived, including its famous rose windows.
On the evening of the blaze, rescuers were intent on saving the relics inside — including what Catholics believe is the crown of thorns that Jesus wore during the Passion — as well as Notre Dame's great organ and its 8,000 pipes, along with the building itself.
Retired French Gen. Jean-Louis Georgelin was chosen by French President Emmanuel Macron to lead the cathedral’s restoration.
"Nothing is impossible to a French general," Georgelin told ABC News’ David Muir in an exclusive interview, saying that he agrees with Macron that Notre Dame could reopen within five years. But, he said, "When there's a will, there's a way."
