E.I. du Pont’s home was a Georgian-style structure located above the powder mills. Considering the frequency of explosions at the mills below, the house sustained damage so many times that du Pont kept lots of spare window glass in the barn. One large explosion caused extensive damage requiring the family to move to another location while the house was rebuilt. Factory buildings below the house were never rebuilt, and were replaced with a Greek-inspired gardens. However the ground was unstable and the gardens have fallen in on themselves.
As the company grew, du Pont moved the company offices into a separate building adjacent the house. The office filing system was a series of wooden cubbyholes. The office safe was not meant to protect cash, but rather to protect the company books and records from the frequent explosions.
Fall colors brighten the hillside above the du Pont mansion.
One of the barn out buildings and ice house are made from the local stone abundantly found in the area.
There are several shallow dams on the Brandywine River to insure sufficient water for the mill to operate.
The Hagley Mills building is now the visitor center and museum. Maples in fall colors provide bright splashes of orange and red.
