Garryowen is a private town in Big Horn County, Montana, United States. It is located at the southernmost edge of the land where Sitting Bull's camp was sited just prior to the Battle of the Little Bighorn, and the opening gunshots of the battle were fired only a few hundred yards from where Garryowen's structures stand today.
Garryowen has a population of just 2 and consists mainly of a large building (the "Town Hall") with multiple functions. This building houses a Conoco petrol station and convenience store, a Subway sandwich franchise, an arts & crafts store called "The Trading Post," and the Custer Battlefield Museum, a private museum whose exhibits focus on the battle and the period of the Indian Wars. Garryowen is owned by Chris Kortlander, and it was put up for sale in 2012, but an auction in August of that year was cancelled after no one registered to bid.
