the location and purpose of several structures were determined through a combination of archaeological and historical work. a map of the fort drawn by de brahm suggested the powder magazine was located in the northwest corner of the fort, and it was in this area that excavators discovered the location of the only structure in the fort built with stone walls, consistent with the design of contemporary powder magazines. excavators uncovered what was likely an ash pit from a forge in the southeast corner of the fort, where de brahm indicated the fort's blacksmith shop was located. a 1757 letter from demeré indicated the fort's guardhouse had a double chimney. excavators noted the only structure in the fort with a double chimney was an elongate building adjacent to the east gate, a position consistent with guardhouse placement at the time. a string of hearths in the western section of the fort indicated the location of the fort's barracks.
