Tour Triangle
proposed skyscraper in Paris, France

The Tour Triangle (French pronunciation: [tuʁ tʁiɑ̃ɡl]; lit. 'Triangle Tower'; also known as the Projet Triangle, or simply Triangle during the planning phase) is an under-construction skyscraper at the Parc des Expositions de la Porte de Versailles in Paris's Rive Gauche, France. Designed by the Swiss firm Herzog & de Meuron, it takes the shape of a 180 m (590 ft) tall glass pyramid with trapezoid base, wide from one side and narrow from another.
Description
The Tour Triangle will be a triangle-shaped building that culminates at 180 metres (590 ft).
The Swiss architecture practice Herzog & de Meuron, which had previously designed the 'Bird's Nest' Olympic stadium in Beijing, was chosen to design the project.
In April 2011, VIPARIS, the project owner, was given the green light for Triangle. The tower site is located next to Porte de Versailles in the Parc des Expositions (southwest of Paris).
The plans for the construction of the tower were initially rejected by Paris councillors on 17 November 2014. A second ballot on the matter by the Paris Council on 30 June 2015 approved the building. Critics of the Tour Triangle had opposed the project because of its controversial height.

Why this record matters
“Tour Triangle” is worth following because a concise public description often conceals a longer documentary argument. Here, Tour, Triangle and proposed provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jun 10, 2026. The linked authority identifier is Q3533204. Authority coordinates are 48.832, 2.286. 2 of 3 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2011, 2014 and 2015.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
