The Avenue of Kings: A Portrait of Avenue Foch

If the Champs-Élysées is the "world’s most beautiful avenue," Avenue Foch is arguably its most aristocratic. Stretching majestically from the Arc de Triomphe to the edge of the Bois de Boulogne in the 16th arrondissement, it is a street that was designed not for commerce, but for prestige.

At 120 meters wide—the widest avenue in Paris—it is a study in silence, wealth, and history.1 Unlike its commercial neighbor, you will find no luxury flagship stores or car showrooms here. Instead, Avenue Foch is a sanctuary of private palaces, hidden behind screens of chestnut trees and manicured lawns, representing the pinnacle of Parisian "old money" and international power.

I. From Empress to Marshal: A History of Names

The avenue was born from the ambitions of Emperor Napoleon III and his prefect, Baron Haussmann, during the radical transformation of Paris in the mid-19th century.2 Opened in 1854, its original purpose was grand but simple: to provide a magnificent approach to the newly created Bois de Boulogne, allowing the city's elite to promenade in their carriages.3

Originally named Avenue de l’Impératrice (Empress Avenue) in honor of Empress Eugénie, it was designed by Adolphe Alphand, the engineer responsible for Paris's parks.4 Alphand didn't just build a road; he built a parkway.5 He lined the avenue with 4,000 trees and wide grass verges ("pelouses"), a feature that remains unique in Paris today.

Following the fall of the Second Empire in 1870, the street underwent an identity crisis mirroring France's political turbulence.6 It became Avenue du Général-Uhrich, then simply Avenue du Bois de Boulogne (or "Avenue du Bois" to the locals).7 It wasn't until 1929, the year of his death, that it was renamed Avenue Foch to honor Marshal Ferdinand Foch, the supreme Allied commander during World War I.8

The Dark Years: Avenue Boche

The avenue’s history is not without its shadows. During the Nazi occupation of Paris (1940–1944), the street was requisitioned by the German military command due to its luxurious real estate. It was grimly nicknamed "Avenue Boche" by Parisians.9

The majestic buildings at numbers 31, 72, and 84 became the headquarters of the Gestapo and the majestic spaces were turned into interrogation centers.10 The Liberation of Paris in August 1944 saw intense fighting here, eventually leading to the avenue reclaiming its dignity as a symbol of French resilience.

II. Architecture and the Contre-Allées

What makes Avenue Foch architecturally distinct is its layout. The central thoroughfare is separated from the residential buildings by wide strips of greenery and service roads known as contre-allées.11

This design serves a dual purpose:

1. Privacy: The residents are set back from the main traffic, insulated by gardens.
2. Social Theater: In the Belle Époque, these side alleys were the stage for high-society horse riding.12

The buildings themselves are a catalogue of late 19th-century opulence.13 While you will find the classic Haussmannian ashlar stone styles, Avenue Foch is famous for its eclecticism. You will see Neo-Renaissance palaces, Louis XVI-style mansions, and Art Deco masterpieces.14

Notable architectural gems include:

• No. 19: An exquisite Hôtel Particulier built for the Ephrussi de Rothschild family.15
• No. 34: The Hôtel Blumenfeld, a stunning example of the flamboyant style preferred by the "nouveaux riches" of the late 1800s.

III. The Gotha: Famous Residents

For over a century, an address on Avenue Foch has been a prerequisite for entry into the global elite.16 It has hosted royalty, tycoons, and artists of the highest caliber.17

The Artists

• Claude Debussy: The legendary composer lived at No. 24 (formerly No. 80 Avenue du Bois) for over a decade. It was here that he composed La Mer.
• Marcel Pagnol: The beloved French novelist and filmmaker resided at No.18 16.
• Maria Callas: The opera diva lived in a sprawling apartment at No. 88 during the height of her fame and her tumultuous relationship with Aristotle Onassis.

The Tycoons and Dynasty

• Aristotle Onassis: The Greek shipping magnate owned an apartment in the same building as Callas.
• The Rothschilds: Various members of the banking dynasty have owned properties along the avenue, cementing its reputation as a hub of financial power.19
• Arthur Rubinstein: The piano virtuoso lived at No.20 22, in a home that became a gathering place for the musical elite.

The Modern Era amp; Controversy

In recent decades, Avenue Foch has attracted a different kind of wealth: foreign royalty and heads of state. This has occasionally led to controversy, most notably the "Biens Mal Acquis" (Ill-Gotten Gains) affair. The mansion at No. 42, a 100-room palace with a nightclub and hair salon, was seized by French authorities from Teodoro Nguema Obiang Mangue (Vice President of Equatorial Guinea) and sold.

IV. The Real Estate Market: The Price of Prestige

Real estate on Avenue Foch operates in a stratosphere of its own.21 It is distinct from the trendy Marais or the intellectual Saint-Germain-des-Prés. This is a market of "Safe Haven" assets for international investors.

The Prices

As of late 2024/early 2025, real estate prices on Avenue Foch generally range between €12,000 and €20,000 per square meter, though exceptional properties can exceed €25,000 per square meter.

While these price-per-square-meter figures are sometimes lower than the ultra-exclusive Avenue Montaigne (which can hit €35,000/m²), the ticket price on Avenue Foch is often higher.

• Why? Because the properties are massive. You rarely find a 50m² pied-à-terre here. Apartments are typically 250m² to 600m².
• Entry Level: A "standard" apartment will cost between €3 million and €5 million.
• Top Tier: Penthouses and private mansions range from €10 million to over €40 million.

Types of Properties

If you are buying on Avenue Foch, you are likely looking at one of three types of property:

1. L'Appartement de Réception (The Grand Apartment): These are the standard units in the Haussmannian buildings. They are defined by the "Galerie d'Entrée" (a long entrance gallery), soaring ceiling heights (3.5 to 4 meters), "Parquet Versailles" flooring, and intricate moldings. They are designed for entertaining, often featuring triple reception rooms facing the avenue.
2. L'Hôtel Particulier (The Private Mansion): These are standalone townhouses, often set behind heavy iron gates. They are incredibly rare in Paris.22 They usually feature private gardens, swimming pools (dug into the basements), and staff quarters.
3. The Service Quarters (Chambres de Bonne): On the top floors, the former maid's rooms have often been combined to create smaller, yet prestigious, penthouses with views of the Eiffel Tower and the Arc de Triomphe.

Who Buys Here?

The demographic has shifted from the French aristocracy of the 1900s to a global clientele today.

• Middle Eastern Royal Families: For privacy and security.
• American & Asian Investors: Attracted by the "postcard" perfection of the location.
• Captains of Industry: Seeking proximity to the business hub of La Défense (accessible via the west) and the Golden Triangle.

Conclusion

Avenue Foch remains a paradox. It is the widest street in Paris, yet it feels like a private club. It is steeped in the history of the 19th century, yet acts as a fortress for modern capital. To walk down Avenue Foch is to witness the architectural timeline of French power, standing as a quiet, green, and incredibly expensive testament to the enduring allure of Paris.
