1. Ironmaster's Mansion Marker
The ruins before you are the remains of a mansion, built ca. 1785 and known for centuries as the Ironmaster's Mansion or Catoctin Manor. The enormous house was surrounded by out-buildings, including quarters for the enslaved domestic servants and a carriage house.
As you look at these ruins, imagine the work required to keep the manor running. Enslaved men, women, and children laid fires in each of the 10 fireplaces, cleaned the massive windows, and prepared lavish meals. The house reflected wealth and prosperity, but at the cost of human freedom. Do you think the enslaved domestic servants dreamed of their ancestral home in Africa and of being free? What do you think the ironmaster and his family thought about the people who were forced to labor on their behalf? These residents of Catoctin Manor lived at the same time and occupied the same space, yet their lives were dramatically different.

» This photograph was taken in 1936. One year later the last resident moved from the mansion and it was abandoned. Under first federal and then state ownership, the mansion was allowed to slowly deteriorate. The ruins have been stabilized but provide little clue of the grandeur this late 78th century mansion once possessed Photograph from the HABS Collection, courtesy of the Library of Congress.
