Lancaster welcomes the Thaddeus Stevens & Lydia Hamilton Smith Center for History and Democracy with a Grand Opening Weekend on May 1 and 2, 2026, where guests can enjoy free community events and get a first look at this new, world-class museum.

This new museum from Lancaster History explores the interwoven lives of Stevens, a 19th-century political leader; and Smith, his housekeeper, a trailblazing Black businesswoman and an individual of extraordinary perseverance.
