September 12, 2023 archaeologists from EAC/Archaeology in Baltimore began their work at the front of Hammond-Harwood House. They are investigating areas where the grass and sidewalk meet, looking for evidence of prior fencing and paving techniques. So far, they’ve found many oyster shells and brick fragments. Evidence of a posthole from a post and chain fence was uncovered about 15 inches in from the sidewalk. Old photos show that this fence existed in the late 1920s through the 1930s, when St. John’s College owned Hammond-Harwood House.
