Dreaming of a building to call home, the Museum Association became temporary tenants in the Carnegie Library Building in Dallas. The first Polk County Museum was open for business.
A new, larger facility was realized when Polk County government provided a 99-year lease on the southwest corner of the Polk County Fairgrounds.
In the fall of 1999, the current museum opened its doors to the public. In 1974, PCHS also acquired the Harrison Brunk pioneer farm site.
