The theater was constructed at the same time the town was built in 1924-25 in order to serve the employees of the oil refinery. The town of Sinclair was founded by oil magnate Frank Kistler, who originally named it Parco. The name came from the acronym PARCO, which stands for Producers and Refiners Corporation, the oil company that Kistler owned. The town’s name was changed when PARCO was bought by Sinclair Consolidated Oil Corporation in the early 1940s. Fisher and Fisher, an architectural firm based out of Denver, designed most of the original town. To promote a sense of visual unity in the new town, they incorporated a Spanish Mission style motif into most of their buildings, which can still be seen in many of the remaining structures, including the theater. It is attached to the recreation building, post office, and fire and police department buildings. Two gabled towers distinguish the front of the theater from the rest of the building. As can be seen in the historical photo above, an arched colonnade once spanned the front of the building that has since been removed. The exterior walls are finished with stucco and the roof is covered with red clay tiles.
