The Adams Museum & House in Deadwood is considered the Black Hills' oldest history museum. Artifacts on display reflect the legends of Wild Bill, Calamity Jane, Deadwood Dick, and the Black Hills Gold Rush. The museum is open year-round and features changing exhibits and special programs.^[1] It was founded by Deadwood businessman and former mayor W.E. Adams in 1930.

The Historic Adams House (44°22′19.60″N 103°43′36.26″W) was built in 1892 by Deadwood pioneers Harris and Anna Franklin. The elegant Queen Anne-style house heralded a wealthy and socially prominent new age for Deadwood, a former rough and tumble gold mining town. In 1920 W.E. Adams bought the house as a tribute to the Black Hills pioneers and in remembrance of his deceased first wife, daughter and granddaughter. The Historic Adams House is completely furnished with original Adams Family furniture and restored interiors.^[3] The house is located at 22 Van Buren Avenue in Deadwood.
