Don’t miss this opportunity to visit the Yturri-Edmunds Homestead Historic site for free! Miss Ernestine E. Edmunds, granddaughter of Manuel Yturri Castillo, willed this two-third acre tract to the Society, which took possession of the property in December, 1961. Yturri Castillo had received the land grant, originally part of Mission Concepcion lands, in 1824 from the Mexican Government. Built between 1840 and 1860, the house is one of the few adobe-block houses remaining in San Antonio. View on Google Maps.
