$55M plan to give Notre Dame a green facelift is part of Paris eco plan

PARIS — As Notre Dame gears up to reopen its doors in December, Paris is on the verge of a remarkable eco-revival, bringing nature back to the forefront of the City of Light.

Beyond restoring the cathedral’s iconic spire and medieval charm, the city announced plans Tuesday to revamp Notre Dame’s surroundings — to a tune of 50 million euros ($55 million) — into a serene, green oasis.

The project echoes a broader, post-Olympics eco-facelift that’s reshaping Paris from its historic monuments to its bustling avenues.

Among the key elements of this broader transformation are the revitalization of historic spaces like the Champs-Elysees and Place de la Concorde, a redesign aimed at reducing traffic around the Arc de Triomphe, and green promenades connecting the French capital’s landmarks.

Here’s a look at some of the eco plans for Paris in the coming years:

Notre Dame Cathedral: a rebirth in green

The reopening on Dec. 8 promises to be a historic moment for Paris, fulfilling President Emmanuel Macron’s vow made after the 2019 devastating fire for a five-year timeline. While the cathedral’s spire and oak-framed roof have been restored to their pre-fire glory, Paris City Hall’s plans for the area around Notre Dame are bringing something new.

The ambitious, future-facing project will create 1,800 square meters (around 20,000 square feet) of green space and plant 160 trees, according to a news conference at City Hall that featured speeches from Paris officials, including Mayor Anne Hidalgo on Tuesday.

Hidalgo stated that the redesign will integrate nature and the Seine more fully into the area. Hidalgo emphasized that this transformation aims “to better highlight our beautiful cathedral and do it justice, while respecting its history.”

The redesign includes transforming the underground parking area into a visitor space complete with services and amenities. Additionally, the Seine’s adjacent quays will be revitalized, offering a new promenade along the river. A belvedere will provide panoramic views of the Ile Saint-Louis and the Seine, further enhancing the visitor experience.

The project will unfold in two phases, with the first, focusing on the parvis and surrounding streets, expected to be completed by the end of 2027. The second phase, which will include the renovation of Square Jean-XXIII and other nearby areas, is set to finish by 2030.

Place de la Concorde: a transformation

At the heart of Paris, the Place de la Concorde — home to the 3,300-year-old Luxor Obelisk — will undergo a significant overhaul between 2026 and 2027.

Paris officials have enlisted the input of a dozen architectural experts to envision how to preserve its rich history, while aligning the plaza with the city’s modern green ambitions. Expect more greenery and less traffic as the revamp balances historical significance with a fresh eco-friendly design.

Eiffel Tower dispute

Not everything has been a picnic in Paris’s post-Olympics makeover.

Two of France’s most high-profile female politicians — Hidalgo and Culture Minister Rachida Dati — are engaged in a fierce battle over the future of the Eiffel Tower, casting a shadow over the city’s plans for its famed monument.

Hidalgo has proposed to keep the Olympic rings affixed to the Eiffel Tower beyond the Games, which ended in August. She argues that the rings symbolize the “festive spirit” of the successful Paris Olympics and wants them to remain at least until the next Summer Games in Los Angeles in 2028.

Critics, however, say Hidalgo is using the Eiffel Tower as a political billboard to boost her image before the 2026 mayoral election, in which she is expected to face off against Dati.

Dati has been vocal in opposing the plan, arguing that the tower is a protected heritage site and can’t be altered without proper consultation. She has accused Hidalgo of using the monument as a “personal campaign poster,” while Hidalgo counters that the rings are a harmless tribute to Paris’ Olympic success.

Dati has gone further, launching an ultimatum to push for the Eiffel Tower to be classified as a full historical monument — something Hidalgo has resisted. This would add extra layers of bureaucratic protection and control, potentially thwarting Hidalgo’s plans.

Champs-Elysees: a greener avenue

Paris’ Champs-Elysees, sometimes called “the most beautiful avenue in the world,” is receiving a 30-million-euro facelift, beginning with the renovation of its sidewalks, tree bases, and gardens that began in preparation for the Olympics.

With 150 proposals to “re-enchant the Champs-Elysees” over the coming years, this project aims to add even more green spaces and revive its historic charm, reinforcing its reputation as the world’s most beautiful avenue.

Arc de Triomphe: reducing traffic

Changes to the Arc de Triomphe’s bustling roundabout are designed to reduce traffic flow and calm the surrounding environment.

Traffic lanes encircling the famous monument will be trimmed, while the central ring will be widened, allowing for a quieter, more accessible space.

Leading from the Arc de Triomphe to the Bois de Boulogne, the Avenue de la Grande Armee is also getting the green treatment. Authorities plan to recreate a historic green promenade, transforming this major traffic artery into a lush, tree-lined boulevard that reconnects the avenue with the nearby forest, historically converted into a public park in the 19th century under Napoleon III.

Louvre Museum to go eco-friendly

Paris’ Louvre Museum, the world’s most visited, will undergo its own transformation under the “Louvre 2030” project.

Though specific details remain sparse, the project aims to address the growing influx of visitors, with a significant redesign of Place du Louvre planned to help manage the crowds and provide a more tranquil, green environment for visitors.
