Center of New Industries and Technologies

Located in the heart of La Défense, the bustling business district in the western suburbs of Paris, the Center of New Industries and Technologies (Centre des nouvelles industries et technologies), commonly known as the CNIT, stands as a testament to modern architectural ingenuity and industrial progress. This iconic structure, with its distinctive arching roof, has been a landmark since its completion in 1958 and continues to draw visitors with its blend of historical significance and contemporary functionality.

The Birth of an Icon

The idea for the CNIT was conceived in the early 1950s by Emmanuel Pouvreau, the president of the machine tools manufacturers' association. His vision was to create a grand exhibition center for industries, initially named the Centre national des industries et techniques. This vision was fueled by the need for a suitable venue to host the machine tools manufacturers' exhibition, a necessity underscored by the inadequate facilities at the Porte de Versailles in Paris, where the event was previously held.

After years of relentless promotion and fundraising, Pouvreau's dream began to materialize. In 1956, the Société Anonyme du Centre national des industries et techniques was established with a capital of 2.2 billion francs, ensuring the project's financial viability. The chosen site was a triangular plot of land in Puteaux, previously occupied by the Zodiac factory, marking the nascent stages of what would become La Défense business district.

A Marvel of Modern Architecture

The construction of the CNIT was a groundbreaking feat of engineering and architectural design. The building's most remarkable feature is its vast self-supporting concrete vault, which spans 218 meters and covers an area of 22,500 square meters. This innovative design, conceived by the architects Robert Camelot, Jean de Mailly, and Bernard Zehrfuss, along with the structural engineer Nicolas Esquillan, set a world record for its sheer size and minimal thickness of just 6 centimeters.

The CNIT's vault is supported by three massive concrete abutments, each weighing 84 tons and interconnected by steel cables. This structural ingenuity not only provided an expansive, unobstructed interior space but also became a symbol of post-war modernism and technological advancement. The building was inaugurated on September 12, 1958, by General Charles de Gaulle, with Culture Minister André Malraux famously declaring, Since the great Gothic cathedrals, nothing like this has been achieved!

Evolution Through the Decades

Initially, the CNIT hosted numerous prestigious exhibitions, including the International Flower Show, the Salon de l'Enfance, and the Paris Boat Show. However, the construction of the La Défense esplanade in 1978, which elevated the ground level and partially buried the CNIT, led to a decline in its exhibition activities. The building's entrances were reconfigured, and its exhibition space was no longer sufficient to meet modern standards.

In 1988, the CNIT underwent its first major restructuring. The interior was completely revamped to create 200,000 square meters of new space, including offices, a luxury hotel, and a shopping area. The renovation, led by architects Andrault and Parrat, Torrieri and Lamy, with Zehrfuss as a consultant, also introduced a state-of-the-art technology center called Infomart. Despite these efforts, the renovation faced challenges, including underutilized office space and insufficient natural light.

The most recent transformation of the CNIT took place between 2006 and 2009 under the ownership of Unibail-Rodamco. This renovation, spearheaded by architects Cuno Brullmann and Jean-Luc Crochon, restored the building's original exterior form by partially demolishing the surrounding esplanade. The interior was redesigned to enhance natural light and create additional office and retail spaces. The CNIT was re-inaugurated on October 21, 2009, marking a new chapter in its storied history.

Today’s CNIT: A Hub of Activity

Today, the CNIT is a vibrant multi-purpose complex that complements the nearby Westfield Les Quatre Temps shopping center. It houses numerous retail outlets, including the popular Fnac store, as well as a Hilton hotel. The building also serves as the headquarters for the Campus Voyages SNCF, which includes various SNCF subsidiaries, and hosts a campus of the prestigious ESSEC Business School.

Although the CNIT no longer functions as a major exhibition center, its legacy as a pioneering architectural and industrial landmark endures. Visitors can explore the building's unique design and enjoy its modern amenities, all while appreciating the historical significance of this remarkable structure.

Getting There

The CNIT is easily accessible via public transportation. It is served by the La Défense station, which connects to Paris Metro Line 1, RER Lines A and E, Transilien Lines U and L, and Tramway Line 2. This makes it a convenient destination for both tourists and business travelers looking to experience one of the most iconic buildings in the La Défense district.

In conclusion, the Center of New Industries and Technologies is not just a building; it is a symbol of innovation, resilience, and the forward-thinking spirit of post-war France. Whether you are an architecture enthusiast, a history buff, or simply looking to explore a unique part of Paris, the CNIT offers a fascinating glimpse into the evolution of modern industry and technology.
