The two-story piazza is the Mansion’s most distinctive architectural feature. Extending the full length of the back of the house, it also has a practical function—catching the river breezes on a hot and humid Virginia day. The Washingtons treated the piazza as an outdoor room, serving afternoon tea here to visitors and family members seated in simple Windsor chairs.
From the piazza, visitors observe a thickly wooded area which was an 18-acre deer park, a common feature on large estates of that time. Washington stocked his with tame deer from nearby and from England for the delight of family and visitors. The trees between the Mansion and the river were carefully pruned to emphasize the view of the Potomac, creating a so-called “hanging wood.”
