San Francisco

San Francisco is a popular international tourist destination, renowned for its chilly summer fog, steep rolling hills, eclectic mix of Victorian and modern architecture and its famous landmarks, including
the Golden Gate Bridge, cable cars, and Chinatown. The city is also a principal banking and finance center, and the home to more than 30 international financial institutions, helping to make San Francisco eighteenth place in the world's top producing cities, ninth in the United States, and fifteenth place in the top twenty Global Financial Centers.

San Francisco is located on the West Coast of the United States at the tip of the San Francisco Peninsula and includes significant stretches of the Pacific Ocean and San Francisco Bay within its boundaries. Several islands - Alcatraz, Treasure Island, and the adjacent Yerba Buena Island, and a small portion of Alameda Island, Red Rock Island, and Angel Island are part of the city. Also included are the uninhabited Farallon Islands, 27 miles (43 km) offshore in the Pacific Ocean. The mainland within the city limits roughly forms a "seven-by-seven-mile square," a common local colloquialism referring to the city's shape, though its total area, including water, is nearly 232 square miles.

San Francisco is famous for its hills. There are more than 50 hills within city limits. Some neighborhoods are named after the hill on which they are situated, including Nob Hill, Pacific Heights, and Russian Hill. Near the geographic center of the city, southwest of the downtown area, are a series of less densely populated hills. Twin Peaks, a pair of hills resting at one of the city's highest points, forms a popular overlook spot. San Francisco's tallest hill, Mount Davidson, is 925 feet (282 m) high and is capped with a 103 foot (31 m) tall cross built in 1934. Dominating this area is Sutro Tower, a large red and white radio and television transmission tower.

Tourism is the backbone of the San Francisco economy. Its frequent portrayal in music, film, and popular culture has made the city and its landmarks recognizable worldwide. It is the city where Tony Bennett "left his heart," where the Birdman of Alcatraz spent many of his final years, and where Rice-a-Roni was said to be the favorite treat. San Francisco attracts the third-highest number of foreign tourists of any city in the U.S. and claims Pier 39 near Fisherman's Wharf as the third-most popular tourist attraction in the nation. More than 16 million visitors arrived in San Francisco in 2007, injecting nearly $8.2 billion into the economy—both all-time high figures for the city. With a large hotel infrastructure and a world-class convention facility in the Moscone Center, San Francisco is also among the top-ten North American destinations for conventions and conferences
