I ventured into the Peirce-du Pont House at Longwood Gardens to warm up on a very cold day.  The elegant staircase was decorated for the holidays and so I photographed not the staircase itself, but the reflection of the staircase in the adjacent mirrored wall.  The mirror makes for an optical illusion – creating the impression of 2 staircases and a much larger room.  The Peirce-du Pont House was built in 1730 by Joshua Peirce, a Quaker Farmer.  It was later purchased by Pierre du Pont in 1906 in order to save the property and the amazing trees from being harvested.  Thus, the building is now known as the Peirce-du Pont House.
