Medina Street in San Antonio, Bexar County, Texas, built in 1909 across from the I&GN train station in the Cattleman's Square area.","why_significant":"The building is tied to the commercial development of San Antonio around Cattleman's Square and the I&GN railroad, which brought heavy passenger traffic to the area. It is also a local example of a Mission Revival commercial building designed by prominent architect Atlee B. Ayres.","narrative":"Built in 1909 at the corner of Houston and Medina Streets in San Antonio, this three-story brick and stucco building was designed to serve rail travelers arriving at the I&GN station across the street. Businessman Silvia Heimann hired architect Atlee B. Ayres to design it. The ground floor held a saloon, restaurant and drug store, and hotel rooms filled the upper floors; it operated as the I&GN Hotel from 1910 until the 1960s. Its Mission Revival features include stepped parapets, red clay tile and a two-story balcony. Cattleman's Square, once a crossroads for the Chisholm Trail and a gateway to Mexico, declined as rail travel faded. The building was recently rehabilitated, with the historic balcony recreated from photographs and a one-story neighboring building reconstructed as an addition. It is recognized for its role in the commercial growth of the district and as a local example of Ayres's early work in the Mission Revival style.","period_of_significance":"c. 1909 - 1955","architect_builder":"Atlee B.
