I finally had the opportunity to tour Nemours this past Thanksgiving weekend, and it far exceeded my expectations in many ways. Having visited other Du Pont family sites at Winterthur and Hagley, this part of the family story was very interesting. The mansion and gardens are really stunning, yet the furnishings seemed very appropriate, and less like a museum and more like a home. While one of Mount Vernon's dining room chairs resides at Nemours, there are other furnishings that are far less formal. Left essentially intact when Alfred's widow died here in 1970, it's a time capsule presented with great care. The tours only take place three times a day and limited to just 48 people. On arrival by bus from the visitors center, groups are divided into four or five people with their own docent. Our guide, Maureen, was very informative, with a sly sense of humor and irony, and made us feel as if she was welcoming us to her own home. Touring the grounds in late fall, the fountains were off and the pools drained, but the formal French gardens were no less spectacular. Nemours is a must-see. Plan ahead and enjoy this as part of the attraction-rich Brandywine Valley.

This like a lot of gilded age mansions is truly spectacular .
After the summer mansions in Newport,RI , this is my all-time favorite.
Don't miss the collection of WW1 German helmets .
As a child, I was a caddy for my grandfather on the duPont country club across the road and the rumor was the glass along the stone wall was to keep the other duPont family members out that Alfred was feuding with over his marriage to a second cousin.
I don't know if he's buried under the clock tower, but the AI duPont hospital and the one in Florida do amazing work for very ill children - his will left them millions.
He bought millions of acres in Florida and now that company is called St Joe Paper which still has only a about 500,000 acres left to develop .
This one and duPont's Longwood & Winterthur estates are a few duPont's legacy gifts to my home state.

breathtaking DuPont home. Unfortunately, time constraints made the tour rushed and the guides were cranky - would not take the time to answer questions. Lot's to see - go early in the day when the guides are friendlier and more willing to take their time.

Toured the Nemours Mansion thought it was for a Holiday Display. The mansion is a really must see. The Holiday part was ok. I would recommend this tour to visitors and to locals. It takes about 2.5 hours but it is worth every minute.
