Everything You Need To Know : Alamo Square
Alamo Square is a residential neighborhood and park in San Francisco, California, in the Western Addition. Its boundaries are not well-defined, but are generally considered to be Webster Street on the east, Golden Gate Avenue on the north, Divisadero Street on the west, and Fell Street on the south.
Alamo Square Park, the neighborhood’s focal point and namesake, consists of four city blocks at the top of a hill overlooking much of downtown San Francisco, with a number of large and architecturally distinctive mansions along the perimeter. The park is bordered by Hayes Street to the south, Steiner Street to the east, Fulton Street to the north, and Scott Street to the west. Named after the lone cottonwood tree (“alamo” in Spanish), Alamo Hill, was a watering hole on the horseback trail from Mission Dolores to the Presidio in the 1800s. In 1856, Mayor James Van Ness created a 12.7 acre park surrounding the watering hole, creating “Alamo Square”. 
The Alamo Square Historic District is significant as a continuum of distinguished residential architecture by distinguished architects spanning the period from the 1870’s to the 1920’s. The towered Westerfield House, the renowned “Postcard Row” with its background of the downtown skyline, and the neighboring streetscapes are as identified worldwide with San Francisco as the cable cars and Coit Tower. With a variety of architectural styles, the District is unified in its residential character, relatively small scale, construction type, materials (principally wood), intense ornamentation (especially at entry and cornice), and use of basements and retaining walls to adjust for hillside sites… With a high degree of integrity to its original designs, the District clearly serves as a visual reminder of how businessmen lived two to four generations ago.
