Mr. du Pont was seemingly obsessed with the movement of water and Longshadow clearly demonstrates that. I couldn’t even begin to count the number of water features amongst the gardens. They range from tiny and discrete to ostentatious. Mr. du Pont was such an autodidact that he studied hydro-engineering so that he could personally calculate the figures determining the size of the pumps he would need for the various water features and fountains throughout the property. These pictures will give you an idea of the scope of his vision.
