Greta Swanson, of Hyattsville, right, gazes up toward the top of the Phoenix Shot Tower on East Fayette Street during a tour led by Carroll Mansion docent Matt Hood, center. Annually, 2.5 million pounds of “drop” shot, used for small game hunting, was made in the tower until 1892. The Shot Tower is open for free drop-in visits 10 a.m to noon Saturdays and Sundays through November.
