Lee's Headquarters Artillery Demonstration

During the Battle of Gettysburg, this small stone house — home of 69-year-old widow Mary Thompson — served as the headquarters of Gen. Robert E. Lee. The property surrounding the house played a pivotal role in the severe fighting on July 1, 1863, and was a key position in the Confederate line for the rest of the engagement. 

Today, the landscape and building have been preserved and restored to its wartime appearance by the American Battlefield Trust.

Take the opportunity to step back in time inside the historic home, during this open house, hosted by the Seminary Ridge Museum & Education Center, in conjunction with the American Battlefield Trust. Interpreters will be onsite and available to answer questions and tell the stories of this crucial site. A self-guided interpretive trail, with five signs explaining the dramatic events at the headquarters from July 1-3, 1863, is open daily from dawn to dusk. Additional augmented reality interpretations of the site are also available in the FREE Gettysburg AR Experience app.
