Paris’ Long-Debated Triangle Tower Finally Reaches Full Height

After nearly two decades of proposals, protests, redesigns, approvals, and delays, Herzog & de Meuron’s striking Tour Triangle has officially topped out above the Paris skyline.

Rising 180 meters (590 feet) in the city’s 15th arrondissement near Porte de Versailles, the glass-clad structure now stands as one of the tallest buildings within Paris proper, surpassed only by the Eiffel Tower and Tour Montparnasse.

The tower’s unconventional form is what makes it immediately recognizable. Rather than appearing as a traditional skyscraper, Tour Triangle takes on a sharply tapered, geometric profile that changes dramatically depending on where it is viewed.

From some angles it appears impossibly thin, while from others it reveals its full triangular mass—a deliberate strategy by the architects to reduce its visual impact on the historic cityscape while creating a distinctive new landmark.

Designed by Swiss architecture firm Herzog & de Meuron, the building has been one of the most controversial development projects in modern Paris.

First unveiled in 2008, it faced years of political opposition and legal challenges from critics concerned about its scale and its effect on the famously low-rise character of the French capital.

Construction ultimately began in 2022 after multiple rounds of approvals and court rulings.

When completed, the 42-story mixed-use tower will house offices, a hotel, restaurants, conference facilities, retail spaces, and public viewing areas overlooking the city.

Plans also incorporate sustainability measures, including extensive photovoltaic panels integrated into the building’s southern facade.

Whether viewed as an elegant feat of engineering or a controversial break from tradition, Tour Triangle represents a rare shift in Paris’s architectural trajectory.

In a city where height restrictions have long preserved a uniform skyline, the tower signals an ongoing conversation about density, modernization, and the future identity of one of the world’s most recognizable urban landscapes.
