Two sleeves containing six photographs of the Granville Bastion underneath the Missroon House (40 East Bay Street) as it is being uncovered, and as it is being worked on by Simons & Lapham, in 1925. Photograph 16b is oriented so that the houses across the street can be seen (41 East Bay Street, 43 East Bay Street).
Granville Bastion... "was the fortification that formed the southeast corner of the original line of military works that completely surrounded the settlement of 1680 on Oyster Point" (now known as White Point Gardens or the Battery).
