Like the Pascal Tower, completed five years earlier, the Voltaire Tower consists of two buildings positioned perpendicular to each other. Both projects, led by Henri La Fonta, were designed as a single complex. This complex of buildings of varying importance forms, according to the project manager, “an opening onto the La Défense district.”

To accentuate this effect, the facades of the buildings were standardized. Square grids, semi-reflective glazing, and Silobre granite were used, marking a departure from fully glazed buildings.

Originally built for the Worms bank, the Voltaire Tower housed a collection of contemporary art, including a video installation of several film clips starring Humphrey Bogart by Korean artist Nam June Paik.

Before becoming an architect, Henri La Fonta first tried his hand at sculpture and painting. However, his training at the École Camondo led him to architecture. He gained his first experience in 1951 in Morocco as a collaborator, then returned to Paris in the 1960s. There, he worked for several design offices.

In 1977, he founded his own agency, which quickly made a name for itself thanks to the creativity and conceptual rigor he demonstrated in his work. In La Défense, Henri La Fonta was the main instigator of the office building revival in the 1980s. The business district owes him Les Miroirs as well as the Pascal and Voltaire towers.
