About the Museum

The Ivinson Mansion, now the Laramie Plains Museum, was built in 1892 in Laramie, Wyoming by Jane and Edward Ivinson. Designed by architect Walter E. Ware of Salt Lake City and built by local contractor Frank Cook, the house was regarded as the most significant residence in Laramie at its completion. Edward Ivinson gave the mansion to the Episcopal Church, which used it as a boarding school until 1958. After years of neglect, the house was acquired by the Laramie Plains Museum Association in 1972 and is used as a museum and events center.
