My place of work in the 1850s when the waters lapped up to the stone wall of the market battery. As in a battery of cannon that protected the market. Because City Hall was built in the 1840s on part of the market square that he been there for decades before that. If you click on the picture you will see more detail. Like these bits:
To the left, you see the sign for "A & D Shaw" but I am not sure why there was a sign like that on the front of a government building. Were there businesses in the building, too? In the middle there is the detail to the left, a week glimpse up Market Street. To the right there is the same thing up Brock. The Market Street buildings are still there but there is no awning or porch on the south side as there was back then. An one of the buildings on Brock could be Sipps or Casa Domenico.
