Casablanca is often overlooked by travelers seeking ancient medinas, but for those interested in urban design, it is Morocco’s most significant destination.
Unlike the historic preservation of Marrakech, Casablanca has served as a global laboratory for architects for over a century. From the ornate Art Deco facades of the 1930s to the high-tech glass towers of the present day, the city’s skyline tells the story of a nation moving rapidly toward the future.
While its scale can be intimidating, the city is a safe and rewarding place to explore with the right preparation. Before you head out, be sure to check our guide: Is Casablanca Safe? Your Essential Guide for a Secure Trip.
This evolution is anchored by landmarks like the Twin Center, which redefined the city’s verticality in the 1990s. By exploring the architectural layers of the “White City,” visitors can see how Moroccan traditions have been successfully reinterpreted through the lens of modern international styles.
The Art Deco Heritage: Casablanca’s 1920s – 1930s Expansion
During the early 20th century, Casablanca served as a primary site for architectural experimentation under the French Protectorate. Architects were encouraged to move away from purely European styles to create something unique to North Africa. This resulted in the Mauresque (or Neo-Moorish) style, a hybrid that combined the streamlined, geometric principles of Art Deco with traditional Moroccan decorative elements.
Mauresque Architecture and the Place Mohammed V
The center of this movement is Place Mohammed V, the city’s administrative heart. The buildings surrounding the square were designed to demonstrate French administrative power while paying homage to local aesthetics.
The Grand Post Office (1918)
Designed by Adrien Laforgue, this building is famous for its blue zellige (mosaic tilework) around the main entrance and its interior Art Deco glass and ironwork.
The Palace of Justice (1925)
This structure features a massive monumental portal and intricate stone carvings that mimic the grand gateways of Morocco’s imperial cities like Fes and Meknes.
The Wilaya (City Hall)
Completed in the 1930s, the building’s clock tower is a dominant landmark, blending Italian-influenced arcades with traditional Moroccan woodwork and internal courtyards.
Distinctive Visual Features of Casablanca’s Art Deco
When walking through the “Petit Paris” district (the area around Boulevard Mohammed V), you can identify this period of architecture by several specific recurring features:
- Curved Corners. Many apartment blocks at intersections feature rounded facades, a signature Art Deco trait that helped soften the city’s dense urban grid.
- Geometric Friezes. Decorative bands along the tops of buildings often replace traditional European floral patterns with Islamic-inspired geometric shapes.
- Wrought-Iron Balconies. Intricate ironwork on windows and balconies often incorporates both French Art Deco zigzags and Moroccan floral motifs.
- White Stucco Facades. To combat the North African sun, architects maintained a strict palette of white and cream, giving Casablanca its nickname, “The White City.”
Post-War Modernism and the “Casablanca School”
In the 1950s, Casablanca became a global center for experimental social housing and bold modernist design. As the city expanded rapidly to accommodate its growing workforce, architects moved away from the decorative Mauresque style toward a more functional, raw aesthetic known as Modernism. This period was spearheaded by the GAMMA group (Groupe des Architectes Modernes Marocains), who sought to create urban environments that were both modern and adapted to the Moroccan way of life.
Innovation in Social Housing: The “Nid d’Abeille”
One of the most famous examples of this era is the Nid d’Abeille (Honeycomb) apartments in the Hay Mohammadi district. Designed by architects Georges Candilis and Shadrach Woods in 1952, this building was a revolutionary attempt to provide high-density housing that still respected traditional social habits.
The building is characterized by its deep, cellular balconies that resemble a honeycomb. These were designed to provide privacy and natural ventilation while functioning as “vertical courtyards”—a modern reinterpretation of the traditional Moroccan riad patio.
Today, the building is studied by urban planners worldwide as a pioneering example of climate-responsive architecture in North Africa.
The Rise of the Skyscraper: Immeuble Liberté
Completed in 1951, the Immeuble Liberté (Liberty Building) was the first “skyscraper” in North Africa, standing 17 stories tall. Located at the intersection of several major boulevards, its V-shaped footprint and stark white concrete facade made it an instant landmark of Casablanca’s vertical ambition. It represented the shift toward high-rise living and set the precedent for the office towers that would follow decades later.
Brutalism and Raw Concrete
Following Morocco’s independence in 1956, the city embraced Brutalism—a style defined by the use of raw, exposed concrete (béton brut). Architects like Jean-François Zevaco and Elie Azagury designed public buildings and private villas that utilized dramatic geometric shapes and heavy structural forms. A notable example is the Church of Notre-Dame de Lourdes, whose massive curved concrete walls and brilliant stained-glass windows create a space that feels both ancient and futuristic.

The Twin Center: A Modern Vertical Landmark
Completed in 1998, the Casablanca Twin Center marked a definitive shift in the city’s skyline, transitioning from mid-century low-rise blocks to a modern, vertical business hub. Designed by the renowned Catalan architect Ricardo Bofill, the towers were intended to act as a symbolic “gateway” to the Maarif district, which was rapidly evolving into the city’s primary commercial and high-end shopping area.
Bofill’s Design Philosophy
Ricardo Bofill was known for blending classical architectural proportions with high-tech materials, and the Twin Center is a prime example of this “Modern Classicism.” Standing 115 meters (28 stories) tall, the towers were designed with a focus on symmetry and material consistency.
Bofill chose to maintain Casablanca’s historic color palette by using white stone cladding and glass. This allowed the massive structures to integrate with the surrounding neighborhoods rather than clashing with the city’s traditional light-colored buildings.
The towers are identical rectangular prisms, connected at the base by a shopping mall and office lobby. This clean, geometric approach was a departure from the intricate decorative styles of the past, signaling Morocco’s entry into the globalized architectural landscape of the late 20th century.
The Function of the Towers
The Twin Center was designed as a “city within a city,” intended to provide a self-contained environment for business and leisure.
- The West Tower. Primarily serves as a corporate hub, housing offices for major international and local firms.
- The East Tower. Originally designed for mixed use, it is now best known for housing the Kenzi Tower Hotel.
- The Commercial Base. The towers sit atop a five-story podium that contains a shopping center and underground parking, a configuration that has since been replicated in many of Casablanca’s newer developments.
A Navigational North Star
Beyond their economic function, the towers serve a vital role in the city’s urban navigation. Because Casablanca is a sprawling city with a complex layout, the Twin Center acts as a constant visual reference point. Whether you are in the residential Anfa district or the historic Habous quarter, the silhouette of the towers is often visible, helping residents and visitors alike maintain their bearings within the urban grid.
The Hassan II Mosque: A Contemporary Masterpiece
Completed in 1993, the Hassan II Mosque is the crowning achievement of modern Moroccan architecture. While it serves a traditional religious purpose, its construction was a massive feat of 20th-century engineering that pushed the boundaries of what was possible in contemporary sacred design. Designed by French architect Michel Pinseau, the mosque was built directly over the Atlantic Ocean, a nod to the Quranic verse stating that “the throne of God was built upon water.”
Modern Engineering Meets Ancient Craft
The structure is a rare example of a “smart” religious building. It features a retractable roof that can open in minutes to ventilate the prayer hall or allow worshippers to pray under the stars. At the top of its 210-meter minaret—the second tallest in the world—a laser beam points toward Mecca, with a reach of 30 kilometers. These high-tech additions are seamlessly integrated into a building that utilized the skills of over 10,000 master artisans, who spent years hand-carving the stone, wood, and plaster that decorate the interior.
Technical Innovations
Building on the edge of the ocean presented significant architectural challenges. To protect the structure from the corrosive salt air and the heavy Atlantic swell, engineers used a specialized type of high-performance concrete and a complex system of breakwaters. The prayer hall floor is partially made of reinforced glass, allowing visitors to see the sea crashing directly beneath them. This blend of cutting-edge marine engineering and centuries-old artisanal techniques makes the Hassan II Mosque a unique landmark in the global architectural landscape.
Casablanca is a City in Constant Motion
Casablanca is a city that refuses to be frozen in time. Unlike the preserved medieval cores of other Moroccan cities, its architectural identity is defined by its willingness to evolve. From the geometric experiments of the Art Deco era to the vertical glass of the Twin Center and the engineering marvel of the Hassan II Mosque, the “White City” remains a laboratory for new ideas.
For the modern traveler, Casablanca offers a chance to see the history of the 20th and 21st centuries written in stone and concrete. It is a city that honors its past by using it as a foundation for a bold, vertical future.
