Fodor's Expert Review Nemours Mansion and Gardens
For a look at how the very wealthy lived, visit Nemours Mansion and Gardens, a 300-acre country estate built for Alfred I. du Pont in 1910. This modified Louis XVI château, which underwent a $39 million restoration that was completed in 2008, showcases 102 rooms of European and American furnishings, rare rugs, tapestries, and art dating to the 15th century. The gardens, reminiscent of those at Versailles, are landscaped with fountains, pools, and statuary. The estate can be seen only on guided two-hour tours. Visitors must be at least 12 years old.
