Hermitage Plaza, Mixed-use skyscraper complex in La Défense, France

Hermitage Plaza is a planned mixed-use development in Courbevoie featuring two towers standing 320 meters tall. The complex will house residential units, office spaces, shops, and a hotel within its structure.

The project began in the 2006 Tour Signal competition under the "Renouveau de la Défense" plan, first with a design by Jacques Ferrier, who left in 2008. Norman Foster presented the current twin-tower scheme on 11 March 2009 at MIPIM in Cannes. An intent protocol was signed with EPAD on 19 June 2010 in Saint Petersburg, before Presidents Medvedev and Sarkozy, with delivery then set for 2016.

The name Hermitage Plaza comes from the Russian developer Hermitage Group, led by Emin Iskenderov. The project was to include two auditoriums, a 1,300-seat concert hall, an art gallery and two spas with pools, alongside housing, a 5-star hotel and offices. Local residents grouped in the association Vivre à la Défense opposed the towers.

The site sits directly along the Seine with planned public spaces for visitors to access. Building permits remain valid through May 2026, and the location is well connected by public transport.

The towers feature an interlocking diamond-shaped design with angled facade panels that both shield from sunlight and maximize views across the city. This geometric approach sets the project apart architecturally within the region.
