Archaeology in Action: South Royal Street Site

We excavated the South Royal Street Site, or 1MB510, as part of the I-10 Mobile River Bridge Archaeology Project in 2022. This was one of the largest sites we excavated for our project and is one of three sites at what is referred to as “RV City,” the area under I-10 where RVs are parked during Mardi Gras. Dr. Alex Beebe of South’s Department of Earth Sciences created a 3d model of our excavations at this site.

The South Royal Street site spans the history of Mobile Bay, including Native American, colonial, and American period components. The middle of the site had evidence from colonial-era landscape modifications, including a large hand-dug ditch and other water control features. These features were buried by storm deposits, potentially from the 1772 and 1822 hurricanes.

This site was a residential area from the 1820s until I-10 was constructed in the 1960s. There were about 30 homes within the site boundaries, most of which were wood frame structures, including shotgun houses and Creole cottages. There were also multi-household dwellings, such as tenements and boarding houses, and a few neighborhood businesses, including a corner grocery store, an “eating house,” and an auto repair shop at different points in time.

Because this was a residential area, like most of our sites, we found many privies, or outhouses, during excavation. Notably, at this site, we found our only brick-lined privy of the project behind what was once 309 South Conception Street (below). While brick-lined privies were thought to prevent water pollution and disease by the mid-1800s, most of the privies we’ve excavated were wood-lined, likely due to cost.

As we continue analyzing our finds from this site, we can learn more about the people who lived here through time.
