The DuPont Experimental Station is the main research and development site of DuPont and Chemours. It is a major component of the DuPont Historic Corridor, a section of Delaware Route 141 that traces the history of both the Du Pont family and the DuPont company. The site map is shown in the Figure and the buildings are numbered. The map is not fixed in time in that not all of the building shown existed in the same time frame. Some were demolished before other were built. The site was initiated along the banks of the Brandywine River so the lowest numbers are in the lower left of the map. Expansion has taken place toward the upper right, slowly displacing the DuPont Country Club, so those are the more modern buildings and the more recent history of the site. Each of the business units of the company have had research facilities at the Experimental Station, so the inventions listed below reflect the nature of the research carried out in each building.〔http://www2.dupont.com/Career_Center/en_US/assets/downloads/duPont_r_d_history.pdf〕 == By building == Building 1 Alkyd resins for automotive finishes.

That bunker housed a shooting range that was used to test DuPont powders and other explosives. In later years, it housed a golf ball cannon and high speed photography equipment to measure the Coefficient of Restitution of golf balls made with various DuPont elastomers.
