This residence was begun in 1897, after John B. Armstrong moved the headquarters of his ranch from the Chicago pasture (7 mi. SE) to this site. Built in stages, the house was completed about 1900. The first portion was made of adobe and plastered over. Later a frame wing was added. Changes were made to the front porch after the destructive hurricane of 1919. This structure exemplifies the evolution of a South Texas ranch headquarters.
