A wood-frame Victorian, built between 1893 and 1895 and located on a large cattle ranch on the western edge of Union Gap. Built by Alexander McAllister, a prominent sheep rancher and hops grower from Scotland, this house is the oldest existing and best preserved Victorian house in Union Gap. It was the headquarters for a ranch that once included 10,000 head of sheep, hundreds of acres of hops, a hop kiln, and for a short while a woolen mill. Today, the mill, kiln and other historic farm buildings are gone, but the house remains, evoking the prosperity of the region at the turn of the century.
