Nagle Warren Mansion, Historic house in Cheyenne, Wyoming, US

The Nagle Warren Mansion is a stone residence built in 1888 at 222 East 17th Street, on the edge of downtown Cheyenne on Cattle Barons' Row. Its exterior was covered in stucco in 1960 after the original stone began to crumble. The property holds three buildings: the main house, a stone carriage house now connected to it, and a stone smokehouse.

The house was built in 1888 by merchant Erasmus Nagle using stone materials from nearby Capitol construction work. It became the home of Senator Francis E. Warren in 1910.

The mansion's dining room hosted Presidents Theodore Roosevelt and William Howard Taft after Senator Francis E. Warren bought the house in 1910. From 1929 it belonged to the YWCA, and since 2022 the innkeeper has again held public and private tea parties, dinner parties, and bridal and baby showers there.

The mansion stands at 222 East 17th Street, on the edge of Cheyenne's historic downtown on Cattle Barons' Row. The carriage house is now connected to the main house, and the stone smokehouse still stands on the grounds. Two conference rooms can be booked for private use, and the inn hosts public and private tea parties, dinner parties, bridal and baby showers.

The property still has its original stone carriage house and the old smokehouse from its early days. Six of the guest rooms occupy the former stable building attached to the main structure.
