Alamo Square is a residential neighborhood and park in San Francisco, California, in the Western Addition, a district of the city's fifth Supervisorial district, and are served by several Muni bus lines including the 5, 21, 22, and 24. Alamo Square Park consists of four city blocks at the top of a hill overlooking much of San Francisco, with a number of large and architecturally distinctive mansions along the perimeter. It is bordered by Hayes Street to the south, Fulton Street to the north, Scott Street to the west, and Steiner Street to the east.
The part of the Western Addition surrounding the park is often referred to as the Alamo Square neighborhood. 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 Oak Street on the south. It is characterized by Victorian architecture that was left largely untouched by the urban renewal projects in other parts of the Western Addition. The Alamo Square area contains the second largest concentration of homes over 10,000 square feet (930 m2) in San Francisco, after the Pacific Heights neighborhood.
