The museum opened in 1967 as a department of the Town of Silver City. It offers exhibitions, educational programs for all ages, community-wide events, a quarterly newsletter, The MansardianTM, and a gift store offering regional crafts, local history books, and southern New Mexico souvenir items. It is also a steward for a vast collection of historical objects.
It has gained national recognition for its high standards of operation by being accredited by the American Alliance of Museums--one of only seven museums in all of New Mexico to receive this honor.
