Howling winds could not stop Notre Dame Cathedral’s heart from beating again.

With three resounding knocks on its doors by Paris Archbishop Laurent Ulrich, wielding a specially designed crosier carved from fire-scorched beams, the monument roared back to life on Saturday evening.

For the first time since a devastating blaze nearly destroyed it in 2019, the towering Gothic masterpiece reopened for worship, its rebirth marked by song, prayer, and awe beneath its soaring arches.

The ceremony, initially planned to begin on the forecourt, was moved entirely inside due to unusually fierce December winds sweeping across the Ile de la Cite, flanked by the River Seine.

Yet the occasion lost none of its splendour. Inside the luminous nave, choirs sang psalms, and the cathedral’s mighty organ, silent for nearly five years, thundered to life in a triumphant interplay of melodies.

The restoration, a spectacular achievement in just five years for a structure that took nearly two centuries to build, is seen as a moment of triumph for French President Emmanuel Macron, who championed the ambitious timeline – and a welcome respite from his domestic political woes.

The evening’s celebration, attended by 1,500 dignitaries, including President-elect Donald Trump, Britain’s Prince William, and Ukrainian President Volodymyr Zelensky, underscored Notre Dame’s enduring role as both a spiritual and cultural beacon.

Inside, 42,000 square meters of stonework – an area equal to six football pitches – were meticulously cleaned, revealing luminous limestone and intricate carvings.

Overhead, 2,000 oak beams, nicknamed “the forest”, were used to rebuild the spire and roof, restoring the cathedral’s iconic silhouette.

The thunderous great organ, with 7,952 pipes ranging from pen-sized to torso-wide, resounded for the first time since the fire.

Its newly renovated console, boasting five keyboards, 115 stops, and 30 foot pedals, was a marvel of restoration, reawakening a cornerstone of Notre Dame’s identity.

Guests gradually filing into the cathedral for the evening reopening ceremonies were awestruck by the renovated interiors, many whipping out mobile phones to capture the moment.

Guests entered through Notre Dame’s iconic western facade, whose arched portals adorned with biblical carvings were once a visual guide for medieval believers.

Inside, the hum of hundreds of guests awaiting the service filled the cathedral with human sounds once more – a stark contrast to the construction din that echoed there for years.

The celebration is expected to give a much-needed boost to embattled Mr Macron, whose prime minister was ousted this week, plunging the nation’s politics into more turmoil.

The French president, who has called Notre Dame’s reopening “a jolt of hope”, will address the gathering. He had hoped the occasion would briefly silence his critics and showcase France’s unity and resilience under his leadership.Macron’s presidency now faces its gravest crisis after the government’s collapse this week in a historic no-confidence vote that toppled Prime Minister Michel Barnier.

Security will be high through the weekend, echoing measures taken during the Paris Olympics earlier this year.

The Ile de la Cite – the small island in the River Seine that is home to Notre Dame and the historic heart of Paris – is closed to tourists and non-residents.

Public viewing areas along the Seine’s southern bank will accommodate 40,000 spectators, who can follow the celebrations on large screens.

For many, Notre Dame’s rebirth is not just a French achievement but a global one – after the reopening, the cathedral is set to welcome 15 million visitors annually, up from 12 million before the fire.
