Golden Gate Bridge
The Golden Gate Bridge is a suspension bridge spanning the Golden Gate strait, the one-mile-wide (1.6 km), three-mile-long (4.8 km) channel between San Francisco Bay and the Pacific Ocean. The structure links the American city of San Francisco, California – the northern tip of the San Francisco Peninsula – to Marin County, carrying both U.S. Route 101 and California State Route 1 across the strait. The bridge is one of the most internationally recognized symbols of San Francisco, California, and the United States. It has been declared one of the Wonders of the Modern World by the American Society of Civil Engineers.
The Frommer’s travel guide describes the Golden Gate Bridge as “possibly the most beautiful, certainly the most photographed, bridge in the world.” It opened in 1937 and was, until 1964, the longest suspension bridge main span in the world, at 4,200 feet (1,300 m).
Alcatraz Island is located in the San Francisco Bay, 1.25 miles (2.01 km) offshore from San Francisco, California, United States. The small island was developed with facilities for a lighthouse, a military fortification, a military prison (1868), and a federal prison from 1933 until 1963. Beginning in November 1969, the island was occupied for more than 19 months by a group of aboriginal people from San Francisco who were part of a wave of Native activism across the nation with public protests through the 1970s. In 1972, Alcatraz became a national recreation area and received designation as a National Historic Landmark in 1986.
Union Square is a 2.6-acre (1.1 ha) public plaza bordered by Geary, Powell, Post and Stockton Streets in downtown San Francisco, California. “Union Square” also refers to the central shopping, hotel, and theater district that surrounds the plaza for several blocks. The area got its name because it was once used for rallies and support for the Union Army during the American Civil War, learning its designation as a California Historical Landmark Today, this one-block plaza and surrounding area is one of the largest collections of department stores, upscale boutiques, gift shops, art galleries, and beauty salons in the United States, making Union Square a major tourist destination, a vital, cosmopolitan gathering place in downtown San Francisco, and one of the world’s premier shopping districts. Grand hotels and small inns, as well as repertory, off-Broadway, and single-act theaters also contribute to the area’s dynamic, 24-hour character.
