In 1890, Welsh immigrant Robert Vaughn perceived a need in the downtown area for the “most advanced livery stable in the West.” This was the genesis of the Arvon Block, a playful take on his name… Robert Vaughn… R. Vaughn… Arvon. The building housed a livery stable, freight transfer office, teamster boarding house and green-grocer. Vaughn, who by that time had received the nickname “The Celtic Cowboy” by the press, would go on to become one of Great Falls’ earliest philanthropists and most prominent citizens. Fast-forward 126 years, The Celtic Cowboy evokes the lively times of the past in what is one of the very few remaining buildings from the early days of Great Falls.
