This is the Roman Catholic Cathedral for the Diocese of Cheyenne, Wyoming. Located in downtown Cheyenne, the cornerstone was laid in 1907 and the cathedral was consecrated in 1909.
This Roman Catholic Cathedral is a contemporary, in terms of construction, to the
Cathedral of the Madeline in Salt Lake City, Utah. I noted this as the
Cathedral of the Madeline, at least according to its corner stone, was originally called St. Mary's Cathedral. In early 20th Century terms Salt Lake and Cheyenne were quite some distance away, but that distance could still be traveled in a day on the Union Pacific, so it's interesting to note that two St. Mary's Cathedrals were being constructed in the region at the same time.
The Cathedral is on a block called "Cathedral Square", which is located across the street in one direction from the
Joseph C. O'Mahoney Federal Courthouse and, in another direction, from the
Wyoming Supreme Court. It is about two blocks away from the
Wyoming State Capitol.
