The Thaddeus Stevens & Lydia Hamilton Smith Center for History and Democracy is an interpretive museum and education center being developed by LancasterHistory, a non-profit organization in Lancaster, Pennsylvania. Set to open May 1, 2026, the Center will examine the long, arduous struggle for freedom and equality in America through exhibits, immersive media experiences, and educational programs.

Housed in the former law office and home of Congressman Thaddeus Stevens and his confidante Lydia Hamilton Smith, the Center will combine historic buildings with a state-of-the-art museum to examine the lives and legacies of Stevens and Smith, and their social networks of abolitionists. The Center’s multi-faceted exhibits—developed in partnership with world-renowned museum designers and noted historians—will address issues of slavery, freedom, and the continuing fight for equality in the United States.
