The Delaware area is house to a very interesting museum that is targeted to the preservation of some very important antiques belonging to Henry Francis du Pont. Initially the whole Winterthur Museum and Country Estate was used as a country house, built in the 18th century and as such it has the period's architectural tone and construction pattern. Winterthur Museum and Country Estate can be located near the Brandywine Creek and it has an astonishing 60 acres of naturalistic gardens that can be visited at any time. However what is most interesting to see is the collection that Henry Francis has gathered during his lifetime, of which of great interest and value is the tambour desk that was created by John Seymour and that, at the time it was purchased, it was valued at an excessive sum of 30,000 dollars. From that on, the collection has expanded. The place is teeming with displays, with an astonishing number of 85,000 objects of the most diverse of nature that can be admired by anybody with an interest. Also the library of the estate is another wonderful display with a number of 87,000 volumes on display and some very interesting manuscripts, in excess of 500,000 of them ready to be viewed and examined. Around the 1990 another zone and type of display has been enforced to the facilities, more informal in nature this time, consisting of some less valuable exhibits displayed in some buildings that were erected more recently.
