Tour Alto
office skyscraper in La Défense's Courbevoie
Tour Alto is an office skyscraper in the Courbevoie commune of the La Défense district in Paris. Built between 2017 and 2020, the tower stands at 160 m (525 ft) tall with 38 floors and is the 21st tallest building in Paris.
History
The Alto Tower is a project financed by SCI White Tower. Development, design, and construction are being handled by Bouygues Construction, in partnership with Linkcity, the real estate development arm of the same group. The architectural design was conceived by IF Architectes and developed in association with SRA Architectes.
The work began in September 2016 and was completed in the first half of 2020. The first steps were the demolition of the existing Saisons building, erected in 1993. and the construction of an underground parking lot, supporting the future forecourt of the Alto Tower.
It measures 160 meters from street level and 150 meters from the La Défense plaza on its eastern façade alone, for a total of 38 floors above ground and 3 underground levels. Its rounded shape gradually widens towards the top with a 12 cm offset outwards.

Why this record matters
“Tour Alto” is worth following because a concise public description often conceals a longer documentary argument. Here, Tour, Alto and office provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Mar 17, 2026. The linked authority identifier is Q16680551. Authority coordinates are 48.889, 2.251. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2017, 2020, 2016 and 1993.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. 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.
