Gibraltar (previously known as the Hugh Rodney Sharp Mansion), located at 2505 Pennsylvania Avenue in Wilmington, Delaware, is a country estate home dating from c. 1844 that is listed on the National Register of Historic Places. It takes its name from the Rock of Gibraltar, alluding to the high rocky outcrop on which the house was built. It is located just inside Wilmington's city limits and originally stood at the center of a much larger estate which has over time been reduced to the present area of about a city block in size. The house was originally built by John Rodney Brincklé and inherited by his brother's wife and children, before being bought in 1909 by Hugh Rodney Sharp, who was linked to the Du Pont family through marriage and work. Sharp expanded and remodeled the house, as well as commissioning the pioneering female landscape designer Marian Cruger Coffin to lay out the gardens.The gardens are now owned by a local preservation trust which acquired it in the 1990s after it was threatened with demolition and redevelopment. They have since been restored and opened to the public. The estate was listed in the National Register of Historic Places in 1998 in recognition of its importance as a well-preserved example of the Country Place era of art and design. The mansion, currently owned by a local developer, has not been occupied for many years and its condition has significantly deteriorated.

The DuPont Experimental Station is the main research and development site of DuPont and Chemours, located along Delaware Route 141. 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.

The DuPont Experimental Station is the largest research and development facility of DuPont. Located on the banks of the Brandywine Creek in Wilmington, Delaware, it is home to some of the most important discoveries of the modern chemical industry.
