It also presents the compound as an unusually detailed, historically accurate example of Hispanic-influenced architecture of the early twentieth century. The 1927 remodel by Spanish architect Antonio Martin and the landscape plan of John McLaren add to its importance.","narrative":"Casa Peralta is a walled residential compound on nearly an acre in San Leandro, California. Its core is a 2½-story Colonial Revival house built in 1901 by Ludovina Peralta, a daughter of Ygnacio Peralta. In the mid-1920s her niece, Herminia Peralta Dargie, widow of Oakland Tribune founder William Dargie, hired Spanish architect Captain Antonio Martin to remodel it as a Spanish country estate. The 1927 work added a four-story tower, tiled walks, fountains, a shrine and a formal garden, while keeping the original Colonial Revival details. Hand-colored tiles illustrating Don Quixote decorate the entrance, alongside adobe bricks salvaged from an 1830 Peralta residence. John McLaren, the longtime Golden Gate Park superintendent, planned the grounds. After Dargie's death the house served as a series of rest homes, and was threatened with demolition in 1971 before local residents bought it and gave it to the city. It is valued for its Peralta family ties and its detailed Hispanic-influenced design.","period_of_significance":"1900- (specific dates 1901; 1927)","architect_builder":"Antonio Martín","architectural_style":"Colonial Revival house remodeled in 1927 in a Spanish Renaissance / Spanish estate manner","criteria":[],"status_note":"Owned by the City of San Leandro and in good condition; described as largely unchanged since 1927.
