The history of the park's building provides visitors with a look into the past. The building represents a transition between Sonoran and Anglo-American architecture with its wood-shingled pitched roof surmounting traditional adobe brick walls. Like most buildings in Territorial Arizona, the original 1878 structure was constructed by hand using native materials. Soil from the area was used to make adobe bricks which were laid on a trench foundation filled with river rocks. All lumber for the floors and roof was hauled by wagon from northern Arizona.
