As part of the long-term plan to improve the State House visitor experience, the 19th century Old House of Delegates Chamber is to be restored, using photographic and documentary evidence from the 1878 redecoration and restoration project directed by Baltimore architect George Frederick. This new space will provide the opportunity to interpret the many important events that took place in the State House and Maryland history in the 19th century, including the abolishment of slavery in Maryland in 1864 and the writing of the state constitution of 1867 that is still in effect today.

The first known floor plan of the Maryland State House, published in the Columbian Magazine in February 1789, shows a classically Georgian plan, with the Old Senate Chamber to the right of the main door and the House of Delegates Chamber to the left. The two chambers were of the same size and were mirror images of each other, with raised podiums - "thrones" for the Speaker and the President - and a gallery at the back of the room. The first meeting of the General Assembly in the new State House took place in the Old House of Delegates Chamber at the start of the March 1779 Session. It was one of the very few rooms in the building that were finished.

Very few substantive changes were made to the House of Delegates Chamber until around 1837, when the desks were painted and six new ones were added to accommodate two more delegates from Baltimore City and four delegates from the newly created Carroll County.

The most dramatic change to the House of Delegates Chamber occurred in 1858 when it was expanded to encompass what has been called the Maryland Silver Room, making it almost twice its original size to accommodate its growing roster of members which reflected the state's increasing population. It was reported that the room was now so commodious for both members and spectators that at least two Constitutional Conventions were held in it, in 1864 and 1867. The Constitution of 1864 was significant historically because it contained a Declaration of Rights that, in its first article, abolished slavery in Maryland. The Constitution of 1867 is still the Constitution of Maryland, with amendments that have passed since its adoption.

In 1878, more renovations guided by the Baltimore architect George Frederick were made to the Chamber and new desks were purchased. Contemporary photographs show a crowded room with an elaborate podium decorated in the high-Victorian style. By the beginning of the 20th century, it was clear that the State House need a major modernization to meet the needs of growing legislative and executive branches of government. The two 19th century annexes were removed and the present Annex was built under the direction of architects Baldwin & Pennington. In 1904, the House of Delegates held its first session in its new chamber.

Since 1904, the space once occupied by the House of Delegates has been used for many different purposes, including as a state museum and as office space for the Department of Legislative Reference. In 1968, a wall was constructed dividing the space into two rooms--the Calvert Room and the Maryland Silver Room. The Calvert Room was a meeting space, and the Maryland Silver Room contained historical exhibits including the display of the USS Maryland silver service.

These two rooms are now being combined and redecorated in the late 19th century, high Victorian style of the Old House of Delegates Chamber. Scheduled to open in early 2011, this will provide an opportunity to interpret the history of the state in the 19th century, an element that has been missing from the State House in recent years.
