In 1993, La Defense is experiencing its second crisis. It was not until 1997 the rebound, evidenced by the construction of towers Coeur Defense, delivered in 2001 by architect Jean Paul Viguier , then the largest such project built in Europe. Heart Defence consists of two towers (161m high) and three 40-storey buildings of 8 floors.
The two towers, connected as Siamese on their height, are narrow (24 m wide) and rounded at each end.
They are offset with respect to each other, which combined with their narrow width, can easily brighten the office.
towers built in 1995 (Michel Andrault, Pierre Parat, Nicolas Ayoub) on behalf of the "Société Générale", measure both 167 meters high (37 floors). The south tower of white stone houses of Chassagne, Chassagne is called and the north tower containing red marble from Alicante, Alicante .

A church on the square ... The Architecture of Our Lady of Pentecost (consecrated in 2001) is special. Designed by architect Frank Hammoutène the heart of La Defense, Our Lady of Pentecost overlooks the highways, giving the impression of being suspended over the void.
She seems to have been made for the site, because its shape is essentially cubic, and it does not adopt the plan or direction to cross the East.
The material used for the main structure is concrete. The church is reported a discreet cross around the entrance. In addition, a facade rises to a height of 35 meters, partly detached from the building, like a steeple. On this concrete wall covered with gray opaque glass windows, two lines of lighter color draw on the full height and full width another cross, as a watermark.
This giant screen, with a thickness of 80 cm, was designed to withstand strong winds that circulate on the square, and is able to bend slightly. It was designed in collaboration with the company Francis Rice Ritchie (RFR). Because of the complex organization of equipment located in the square slab of Defense, the foundations of the building alone accounted for one third of the total cost (we used to 62 cells, some inclined to 20 ° to avoid underground obstacles).
