Located on the east side of the 1722 structure, the “lean-to” chamber is exhibited as a study, though not as a library. Primary source documentation has not yet revealed the actual use of the chamber; we hope to learn as research continues. The room is heated by a fireplace that shares the chimney with the 1797 Passage Room, and well illuminated by three windows. The door leading to the 1797 Passage Room is original to the structure.
