Laramie Plains Museum, The Ivinson Mansion

Jane and Edward Ivinson arrived in Laramie in eighteen sixty-eight, the same year the Union Pacific Railroad came through. They became pillars of the town and by eighteen ninety-two had built themselves a mansion designed by Salt Lake City architect Walter Ware. It was the most significant private residence in Laramie: about eleven thousand seven hundred square feet across three floors.

In nineteen twenty-one Edward Ivinson donated the home to the Episcopal Church, which ran it as a girls' boarding school until nineteen fifty-eight. The Laramie Plains Museum Association acquired it in nineteen seventy-two and turned it into a history museum documenting ranching, railroad life, and the story of the Laramie Plains. It operates as a museum today.
