The church's building was built c. 1883, originally to house Oreana's general store and post office.

When the building was constructed, it was part of a corner which included Oreana's saloon, hotel, and school; the general store building is the only surviving structure from this set.

The lava rock building features a false front and a wooden cornice atop its parapet roofline.

In addition to serving as a general store, the building also house Oreana's first post office, which opened in 1885.

[2] The building was added to the National Register of Historic Places on November 28, 1980.
