Established in 1884, the original Marble Falls Post Office was built south of the Colorado River. William P. Cochran, appointed postmaster in 1901, built this structure in 1910 and leased it to the U. S. Government for use as a post office. It continued to serve as a postal facility until about 1950. Constructed of poured concrete, the building features a central double door with three-pane transom, a simply detailed cornice, and a stone parapet. Recorded Texas Historic Landmark - 1989
