Located in the center of downtown Newark, the Prudential Center site previously included  the Four Corners Historic District and the Old First Presbyterian Church Cemetery, which was converted to a parking lot a parking lot in the 1950s. The project entailed historic research for the property to determine the usage of the property; submitting an Application for Project Authorization to demolish three buildings which were part of the Four Corners Historic District; conducting Historic American Building Surveys on these buildings as part of the resolution; monitoring for human remains during the demolition of the Central Railroad of NJ station as part of the resolution; and exploratory trenching in the former cemetery to determine if any human remains were still interred. Monitoring uncovered 2 sets of human remains and trenching uncovered an additional 40 sets of remains. This resulted in a Phase III Archaeological Data Recovery to remove all human remains still interred in the former cemetery. A group of 60 archaeologists, headed by Langan, worked for 9 weeks identifying and removing over 2,300 sets of remains and associated artifacts.
