Somewhat less elaborate than the Robertson House, but equally dignified, is the Capt. Halley House, built ca. 1860,is built of wood-frame construction with clapboard siding, and has an ell-shaped plan. It exhibits Greek Revival symmetry and proportions in its five-bay fronts which feature double-hung windows with six-over-six lights, and pedimented two-story porticoes supported by square columns. Also typical is the use of simple cornice molding, as well as the presence of a central entrance marked with double doors, transom, and sidelights.
The Armstrong-Adams House, built ca. 1868,is quite modest in size. Nevertheless, it is a fine example of Greek Revival. Constructed of dressed limestone blocks, it’s five-bay front features quoins, flat arches above double-hung windows with six-over-six lights, projecting portico with cornice, and a flat roof supported by square columns..
Begun in 1852 to serve travelers along the old stage route, the Stagecoach Inn is thought to be the oldest remaining structure in Salado. The simple, somewhat primitive wood-frame building of two stories is a good example of frontier vernacular architecture. It features a rectangular plan, and has a two-tiered portico supported by square columns running the length of the front (east) facade. A simple balustrade encloses the second-story balcony. The front facade is broken with a series of single doors and double-hung windows with six-over-six lights placed apparently randomly or as need called for. An addition was made to the rear of the building in the 1940s and again in the 1950s, to accommodate a growing restaurant clientele. These additions are not visible from public approaches to the building,and hence do not compromise the building's historic integrity.
The plantation of Col. Elijah Sterling Clack Robertson is outstanding among the architectural sites. This complex includes a complete assemblage of outbuildings and a residence which is one of the best examples of the Greek Revival style as it was interpreted in Texas. The buildings remain intact in their original setting, and form one of the best-preserved complexes from the plantation era. The facade of the house is divided into five parts, so that the central and two end bays constitute pavilions dominated by gables and separated by galleries. The house is reminiscent of some examples of American late Georgian architecture, and was likely inspired by a house in Tennessee that was the birthplace of the builder (Webb and Alexander). Squared columns support the two-story porticoes with their balustrades, and the central, double-door entrance has both transom and sidelights.Large double-hung windows with six-over-six lights and louvered shutters punctuate the clapboard walls, while dentils accentuate the comice and pediments. In constructing his house. Col. Robertson included a "strangers' room" in one of the end pavilions, to allow newcomers and travelers to lodge at his home without bothering his family. The stone kitchen, originally detached, was joined to the house by an addition made in the 1880s, thus breaking somewhat the symmetry of the plan. Otherwise the house has remained intact through six generations of the Robertson family. Included in the nominated property are the servants' quarters, which is a single-story stone structure of rectangular plan and gabled roof, a stone and wood bam, and the family cemetery in which Col. Robertson is buried.
Possibly the most important non-residential structure in Salado was Salado College (archeological site #41BL241), which was built about 1861. I t now exists only as ruins on a h i l l just south of the creek. The building originally stood two stories t a l l , with the main entrance facing south. The west wall and the northeast comer of the east wall are a l l that survive, and both are i n deteriorated condition amid piles of stone rubble. Examination of the remains, however, reveals a surprising sophistication in the construction of the stone walls, which were once plastered with a lime mortar and scored to emulate smooth, precise ashlar courses. Originally topping the two-story walls was a pronounced cornice with carved-stone molding just beneath the eaves of the roofline.
