History
Half Moon Bay began as a rural agricultural area, primarily used by Mission San Francisco de Asís (established in 1776) for grazing cattle, horses, and oxen. After the Mission's secularization, Tiburcio Vásquez received the Rancho Corral de Tierra Mexican land grant in 1839 and Candelario Miramontes was granted Rancho Miramontes (later known as Rancho San Benito) in 1841. The community began to develop in the 1840s as San Mateo County's first real town. Originally, San Benito, the town was renamed Spanishtown and attracted a thriving fishing industry in addition to its continued importance to coastal agriculture. Spanishtown became a racially diverse community, settled by Canadians, Chinese, English, Germans, Irish, Mexicans, Italians, Scots, Portuguese, and Pacific Islanders. Regular stagecoach service was established with San Mateo; coaches also served Purissima, Lobitos, and San Gregorio. Levy Brothers opened a department store downtown. Spanishtown was officially renamed Half Moon Bay in 1874. The area grew very slowly, even after the Ocean Shore Railroad began serving the community in 1907. The construction of Pedro Mountain Road in 1914 provided better access to San Francisco and probably contributed to the railroad's demise by 1920. The USS DeLong ran aground at Half Moon Bay on December 1, 1921. During Prohibition "rum runners" took advantage of dense fog and hidden coves in the area to serve several roadhouses and inns, some of which operate today as restaurants (e.g., Moss Beach Distillery). Real growth in the area came after World War II with the construction of numerous subdivisions, eventually leading to Half Moon Bay's incorporation in 1959. The city preserves a historic downtown district that has buildings dating as far back as 1869. In 2008,…
