Why is the restoration of the State House imporatant? 

The Maryland State House is a National Historic Landmark and the principal feature of the Colonial Annapolis National Register Historic District. 

It is the location of some of the most important events in the history of our nation, including: 

  • Washington's resignation as commander in chief before the Continental Congress
  • The ratification of the Treaty of Paris
  • The abolishment of slavery in the State of Maryland
  • The 1867 writing of our state's constitution 
As such, the Maryland State House is a significant cultural asset, on both a local and national level. The State of Maryland has preserved the Maryland State House while maintaining its continuous use over a period of nearly 250 years, making it the oldest state house in the United States under continuous legislative use. The Maryland State House must continue to be preserved not only to support ongoing government fuctions which it houses, but to help promote the thousands of visitors who come each year to learn about the rich history of our state and our nation, as well as for future generations to come.
