Avenue Montaigne is the most fashionable street in France. It has also become an exclusive residential neighborhood for the wealthy and famous. This 350-year-old avenue is located in the 8th arrondissement in the Champs-Elysees quarter, where it is steeped in cultural history.

9. Fifth Avenue, New York

Price per square meter: $28,000

The rich and famous have flocked to this street since the 1900s because of its central location and its cachet. The most expensive properties are along leafy Central Park. Prices have soared once again as the U.S. economy has recovered, rising more than 5 percent in the past year.

8. Ostozhenka, Moscow

7. Romazzino Hill, Sardinia

Price per square meter: $32,900

The Aga Khan turned the Costa Smeralda, Sardinia, into his holiday retreat in the 1960s. It has been a destination for billionaires ever since. The street first attracted attention when Italian industrialist Carlo de Benedetti sold his seafront villa Rocky Ram for 110 million euros to a Russian buyer. Some of the location’s most exclusive hotels include the Cala di Volpe and the Romazzino.

6. Chemin de Ruth, Geneva

Located in the heart of Switzerland’s Cologny, close to the shores of Lake Geneva, the Chemin de Ruth is Switzerland’s most expensive street. The mansions on this street have more land than most other streets in the area, with many beautiful landscaped gardens and large swimming pools.

5. Paterson Hill, Singapore

Price per square meter: $42,500

Singapore’s most prestigious residential address is this cul-de-sac. Considered the city-state’s “Billionaire’s Row,” prices here have jumped this past year. It is located in district 09, a tranquil residential area close to the Orchard Road Shopping Belt.

4. Boulevard du Général de Gaulle, Cap Ferrat, France

Price per square meter: $79,000

Cap Ferrat may be the most sought-after piece of land along the Mediterranean Cote d’Azur, making it the world’s most expensive nonurban real estate. Its location about 15 kilometers from Monaco makes it a hot spot for the rich and famous. The Boulevard du Général de Gaulle is the main road that loops around the peninsula, spotted with vast beachfront villas and sprawling, gated gardens.

3. Avenue Princess Grace, Monaco

Price per square meter: $86,000

The most exclusive street in this tiny principality is iconic Avenue Princesse Grace. At the peak of the property boom, prices on the palm tree-lined street surpassed 100,000 euros ($135,000) per square meter. Since the recession, however, values have cooled substantially, now down to an average 65,000 euros per square meter. The majority of developments on this street are now rental-only because of finite space.

2. Kensington Palace Gardens, London

Price per square meter: $107,000 (69,900 pounds)

Kensington Palace Gardens is the world’s second-most-expensive street. Here, properties sell for as much as 122 million pounds ($195 million). The street’s latest arrivals, the Duke and Duchess of Cambridge, who moved in to the road’s eponymous palace, have helped boost prices.

1. Pollock's Path, The Peak, Hong Kong

Price per square meter: $120,000 (HK$930,670)

Pollock’s Path on The Peak is the most expensive street in the world. The mountain has long been home to Hong Kong’s wealthiest people. Chic new developments on this winding path have pushed up prices. Skyhigh, a development at number 10–18 Pollock’s Path, is one of the most prestigious developments on this road.
