The John Harris-Simon Cameron Mansion was built c. 1766 by John Harris, Jr., one of the founders of Harrisburg. In 1863 it was purchased by Simon Cameron, Lincoln's first Secretary of War and later Ambassador to Russia, who transformed the Georgian house into a stylish Victorian mansion and lived there until his death in 1889.

Features illustrating the lives of the house's residents (1766-1929) are a large Victorian parlor, Colonial and Victorian bedrooms, spectacular Art Deco bathroom; light-filled solarium; dining room, library, office, and exhibit spaces.
