Lincoln State Monument manages most of the historical buildings in the community of Lincoln. This most widely visited state monument in New Mexico is part of a community frozen in time—the 1870s and 1880s. The monument includes 17 structures and outbuildings, 4 of which are open year-round and 2 more seasonally as museums. Most of the buildings in the community are representative of the Territorial Style of adobe architecture in the American Southwest. Lincoln is a town made famous by one of the most violent periods in New Mexico history. Today's visitors can see the Old Lincoln County Courthouse with museum exhibits that recount the details of the Lincoln County War and the historic use of the "House" as store, residence, Masonic Lodge, courthouse, and jail. Visitors walk in the footsteps of Billy the Kid, Pat Garrett, and other famous and infamous characters of the Wild West, and trace the events of 1878 through the Courthouse and the Tunstall Store, which contains displays of the original 19th-century merchandise in the original shelving and cases. They can then continue through history by visiting the Dr. Woods House, defensive torreón (tower) for the village; the San Juan Mission Church; and the Montaño store. The Anderson-Freeman Museum features historical exhibits in a timeline starting with American Indian prehistory and ending with the Lincoln County War. A 12-minute video about the Lincoln County War and the community is shown throughout the day.
The site offers a short film, exhibits, and tours.
